1. 前言
本文将HBase-0.98.0安装在Hadoop-2.4.0上,关于Hadoop-2.4.0的安装,请参见《Hadoop-2.4.0分布式安装手册》一文。
安装环境为64位SuSE-Linux 10.1版本。
本文将在HBase官方提供的quickstart.html文件的指导下进行,在docs/getting_started目录下可找到quickstart.html,或直接浏览在线的:http://hbase.apache.org/book/quickstart.html。
安装使用外置的ZooKeeper,有关ZooKeeper的安装,请参见《ZooKeeper-3.4.6分布式安装指南》一文。
关于分布式安装,请浏览:http://hbase.apache.org/book/standalone_dist.html#distributed,关于HBase使用外置的ZooKeeper配置,请浏览:http://hbase.apache.org/book/zookeeper.html。
所有在线的文档,均会出现在二进制安装包解压后的docs目录下。本文的安装环境为64位SuSE 10.1 Linux。
2. 约定
假设将Hadoop-2.4.0安装在/data/hadoop/current目录,而/data/hadoop/current实际是到/data/hadoop/hadoop-2.4.0的软链接。
HBase安装目录为/data/hadoop/hbase,而/data/hadoop/hbase实际是到hbase-0.98.0-hadoop2的软链接。
建议JDK为1.7版本,在JDK1.8上可以成功安装Hadoop-2.4.0,但基于JDK1.8编译Hadoop-2.4.0则会遇到困难。
3. 相关端口
2888 ZooKeeper,如果是Leader,用来监听Follower的连接
3888 ZooKeeper,用于Leader选举
2181 ZooKeeper,用来监听客户端的连接
60010 hbase.master.info.port,HMaster的http端口
60000 hbase.master.port,HMaster的RPC端口
60030 hbase.regionserver.info.port,HRegionServer的http端口
60020 hbase.regionserver.port,HRegionServer的RPC端口
8080 hbase.rest.port,HBase REST server的端口
4. 下载HBase
官网:http://hbase.apache.org/,在这里即可找到下载HBase的链接。
下载国内映像站点:http://mirror.bit.edu.cn/apache/hbase/,HBase-0.98.0版本的下载网址:http://mirror.bit.edu.cn/apache/hbase/hbase-0.98.0/。选择下载hbase-0.98.0-hadoop2-bin.tar.gz。
5. 安装步骤
5.1. 修改conf/regionservers
regionservers类似于Hadoop的slaves文件,不需要在RegionServer机器上执行些修改。
将所有HRegionServers的IP或主机名一行一行的例举在在regionservers文件中,注意必须一行一个,不能一行多个。本文配置如下:
hadoop@VM_40_171_sles10_64:~/hbase/conf> cat regionservers
10.12.154.77
10.12.154.78
10.12.154.79
5.2. 修改conf/hbase-site.xml
需要在所有机器上做同样的操作,可以借助scp命令,先配置好一台,然后复制过去,如:scp hbase-site.xml hadoop@10.12.154.79:/data/hadoop/hbase/conf/。
hbase-site.xml是HBase的配置文件。默认的hbase-site.xml是空的,如下所示:
<?xml version="1.0"?>
<?xml-stylesheet type="text/xsl" href="configuration.xsl"?>

-->
<configuration>
</configuration>
没关系,就用它。不要用docs目录下的hbase-default.xml,这个会让你看得难受。
编辑hbase-site.xml,添加如下内容(摘自standalone_dist.html,搜索“Fully-distributed”):
<configuration>
<property>
<name>hbase.rootdir</name>
<value>hdfs://172.25.40.171:9001/hbase</value>
<description>The directory shared by RegionServers.</description>
</property>
<property>
<name>hbase.cluster.distributed</name>
<value>true</value>
<description>The mode the cluster will be in. Possible values are
false: standalone and pseudo-distributed setups with managed Zookeeper
true: fully-distributed with unmanaged Zookeeper Quorum (see hbase-env.sh)
</description>
</property>
<property>
<name>hbase.zookeeper.quorum</name>
<value>DEVNET-154-77,DEVNET-154-70,DEVNET-154-79</value>
<description>Comma separated list of servers in the ZooKeeper Quorum.
For example, "host1.mydomain.com,host2.mydomain.com,host3.mydomain.com".
By default this is set to localhost for local and pseudo-distributed modes
of operation. For a fully-distributed setup, this should be set to a full
list of ZooKeeper quorum servers. If HBASE_MANAGES_ZK is set in hbase-env.sh
this is the list of servers which we will start/stop ZooKeeper on.
</description>
</property>
<property>
<name>hbase.master.maxclockskew</name>
<value>600000</value>
<description>Time(ms) difference of regionserver from master</description>
</property>
</configuration>
“hbase.zookeeper.quorum”可以填写IP列表。hdfs://172.25.40.171:9001对应hdfs-site.xml中的“dfs.namenode.rpc-address”。“hbase.zookeeper.quorum”配置为ZooKeeper集群各节点主机名或IP。
更多的信息,可以浏览:http://hbase.apache.org/book/config.files.html。
5.2.1. hbase.master.info.port
用于指定HMaster的http端口。
5.2.2. hbase.master.info.bindAddress
用于指定HMaster的http的IP地址,如果不设定该值,可能使用IPv6地址。
5.3. 修改conf/hbase-env.sh
需要在所有机器上做同样的操作,可以借助scp命令,先配置好一台,然后复制过去,如:scp hbase-site.xml hadoop@10.12.154.79:/data/hadoop/hbase/conf/,修改内容如下:
1) 设置JAVA_HOME
# The java implementation to use.Java 1.6 required.
export JAVA_HOME=/data/jdk
上述/data/jdk是JDK的安装目录。
2) 设置HBASE_MANAGES_ZK
# Tell HBase whether it should manage it's own instance of Zookeeper or not.
export HBASE_MANAGES_ZK=false
如果HBASE_MANAGES_ZK值为true,则表示使用HBase自带的ZooKeeper,建议单独部署ZooKeeper,这样便于ZooKeeper同时为其它系统提供服务。
3) 设置HBASE_CLASSPATH
# Extra Java CLASSPATH elements.Optional.
export HBASE_CLASSPATH=/data/hadoop/current/etc/hadoop
6. 启动运行
进入HBASE_HOME/bin目录,执行start-hbase.sh即可启动HBase。请使用JDK提供的jps命令,分别查看HMaster和HRegionServer进程是否已经起来,同时检查日志文件是否有错误。
7. 基本的HBase命令
通过执行“hbase shell”进入命令行操作界面。详细请浏览官方文档:quickstart.html。
hbase(main):003:0> create 'test', 'cf'# 创建表test,一个列族cf
0 row(s) in 1.2200 seconds
hbase(main):003:0> list 'test'
..
1 row(s) in 0.0550 seconds
hbase(main):004:0> put 'test', 'row1', 'cf:a', 'value1'# 往表test的cf列族的a字段插入值value1
0 row(s) in 0.0560 seconds
hbase(main):005:0> put 'test', 'row2', 'cf:b', 'value2'
0 row(s) in 0.0370 seconds
hbase(main):006:0> put 'test', 'row3', 'cf:c', 'value3'
0 row(s) in 0.0450 seconds
hbase(main):007:0> scan 'test'# 扫描表test
ROW COLUMN+CELL
row1 column=cf:a, timestamp=1288380727188, value=value1
row2 column=cf:b, timestamp=1288380738440, value=value2
row3 column=cf:c, timestamp=1288380747365, value=value3
3 row(s) in 0.0590 seconds
hbase(main):008:0> get 'test', 'row1'# 从表test取一行数据
COLUMN CELL
cf:a timestamp=1288380727188, value=value1
1 row(s) in 0.0400 seconds
hbase(main):012:0> disable 'test'
0 row(s) in 1.0930 seconds
hbase(main):013:0> drop 'test'
0 row(s) in 0.0770 seconds
hbase(main):014:0> exit
8. 备HMaster配置
备HMaster可以有0到多个,配置和主HMaster完全相同,所以只需要复制一份已配置好的HMaster过去即可,然后同样的命令启动。启动好后,一样可以执行HBase shell命令。
9. 常见错误
本文的实践过程中遇到了如下一些错误:
1) 错误1:Host key not found from database
遇到如下错误,说明不能免密码登录DEVNET-154-70、DEVNET-154-77和DEVNET-154-79,假设用户名为hadoop,则可以试试ssh hadoop@DEVNET-154-70来检查是否能免密码登录:
./start-hbase.sh
DEVNET-154-70: Host key not found from database.
DEVNET-154-70: Key fingerprint:
DEVNET-154-70: xihad-rotuf-lykeh-mapup-kylin-kybub-sohid-bucaf-gafyg-vecuc-tyxux
DEVNET-154-70: You can get a public key's fingerprint by running
DEVNET-154-70: % ssh-keygen -F publickey.pub
DEVNET-154-70: on the keyfile.
DEVNET-154-70: warning: tcgetattr failed in ssh_rl_set_tty_modes_for_fd: fd 1: Invalid argument
DEVNET-154-77: Host key not found from database.

DEVNET-154-79: Host key not found from database.
DEVNET-154-79: Key fingerprint:

DEVNET-154-79: You can get a public key's fingerprint by running
DEVNET-154-79: % ssh-keygen -F publickey.pub
DEVNET-154-79: on the keyfile.
DEVNET-154-79: warning: tcgetattr failed in ssh_rl_set_tty_modes_for_fd: fd 1: Invalid argument
2) 错误2:Failed deleting my ephemeral node
原因可能是因为之前配置错误,比如使用HBase自带的ZooKeeper启动过,后改为使用外围的ZooKeeper再启动。
2014-04-22 16:26:17,452 WARN zookeeper.RecoverableZooKeeper: Node /hbase/rs/DEVNET-154-79,60020,1398155173411 already deleted, retry=false

at org.apache.hadoop.hbase.regionserver.HRegionServer.run(HRegionServer.java:1003)
at java.lang.Thread.run(Thread.java:744)
3) 错误3:Master rejected startup because clock is out of sync
来自RegionServer端的日志,HMaster拒绝RegionServer的连接。这个错误是因为HMaster上的时间和RegionServer上的时间相差超过30秒。
两种解决办法:
一是同步时间,
二是修改hbase-site.xml中的hbase.master.maxclockskew(HMaster端的hdfs-site.xml文件):。
2014-04-22 16:34:36,701 FATAL regionserver.HRegionServer: Master rejected startup because clock is out of sync

将hbase.master.maxclockskew改成可以容忍10分钟:
<property>

<value>600000</value>
<description>Time(ms) difference of regionserver from master</description>

phoenix的安装
Phoenix的安装非常简单。官网有说明(http://phoenix.incubator.apache.org/download.html),二进制安装包可从http://www.apache.org/dyn/closer.cgi/incubator/phoenix/上下载,本文下载的是phoenix-4.0.0-incubating.tar.gz,注意和HBase的兼容关系:
Phoenix版本
HBase版本
Phoenix 2.x
HBase 0.94.x
Phoenix 3.x
HBase 0.94.x
Phoenix 4.x
HBase 0.98.1+
安装步骤为:
1) 将phoenix-4.0.0-incubating.tar.gz上传到Phoenix客户端机器,假设安装到/data/hadoop
2) 解压phoenix-4.0.0-incubating.tar.gz,解压后生成phoenix-4.0.0-incubating目录
3) 建立软链接:ln -s phoenix-4.0.0-incubating phoenix
4) 将/data/hadoop/phoenix/hadoop-2/phoenix-4.0.0-incubating-client.jar添加到CLASSPATH
5) 将phoenix/common目录下的phoenix-core-4.0.0-incubating.jar复制到所有HBase region server的的CLASSPATH中,比如HBase的lib目录
6) 重启HBase集群
运行phoenix也非常简单,命令格式为:
sqlline.py zookeeper file.sql
示例:

请问,Phoenix能读取hbase中已经存在的表吗?
应该没问题的
bioger_hit 发表于 2014-11-20 11:29
应该没问题的
谢谢您的答复,可是我在Phoenix中执行:$ !tables,只有在Phoenix中建的表,我从hbase shell中执行:$list 有很多表的,其中有Phoenix建的表。是我的配置哪里有问题吗?请指教。
{:soso_e179:} 因为不能发帖,所以只好来回复问点问题,还希望知道的能帮忙解答,也求扩散。
最近公司因为业务需求,需要用到大数据框架,目前已经配置好了hadoop+hbase的集群。刚好看到phoenix这个执行标准SQL的插件,所以也用上了。那么问题来了:
以前我们用mysql或者Oracle,可以用mybatis或者hibernate这样的持久层框架,那么phoenix可以用么?phoenix也有自己的驱动,main方法测试也可以连接上,但是如果用以前Spring+mybatis的方式来管理的,死活是连不上的,不知道有没有人尝试过?或者有相关经历的? 好东西!
