为什么我执行hbase的命令的时候总是报错？

我在centos的命令行中执行hbase时，会报错，大神帮忙看看。
命令：
[root@escmaster bin]# hbase org.apache.hadoop.hbase.snapshot.ExportSnapshot -snapshot Examination-20161202 -copy-to hdfs://escn2:8020/hbase
错误：

……

首先看看这个jar包（hdfs://escmaster:9000/home/hadoop/hadoop/hbase-1.0.0-cdh5.4.10/lib/hbase-client-1.0.0-cdh5.4.10.jar）是否真的存在。
另外命令中缺少了class
hbase class org.apache.hadoop.hbase.snapshot.ExportSnapshot -snapshot MySnapshot -copy-to hdfs://escn2:8082/hbase -mappers 16

下面命令可以查看快照信息
列出快照信息
hbase org.apache.hadoop.hbase.snapshot.SnapshotInfo -list-snapshots

列出包含的文件
hbase org.apache.hadoop.hbase.snapshot.SnapshotInfo -snapshot test-snapshot -files

首先看看这个jar包（hdfs://escmaster:9000/home/hadoop/hadoop/hbase-1.0.0-cdh5.4.10/lib/hbase-client-1 ...

hdfs://escmaster:9000/home/hadoop/hadoop/hbase-1.0.0-cdh5.4.10/lib/hbase-client-1.0.0-cdh5.4.10.jar
这个路径是不存在的，我不明白为什么会到这个路径里面找，我的HBASE的路径:/home/hadoop/hadoop/hbase-1.0.0-cdh5.4.10/lib/hbase-client-1.0.0-cdh5.4.10.jar，这个路径是有的。


我是了下增加class，是另外的错误，是不是什么地方的classpath设置不对？
命令：
hbase class org.apache.hadoop.hbase.snapshot.ExportSnapshot -snapshot Mars_AweEnableInfo-20161202 -copy-to hdfs://escn2:8082/hbase -mappers 16
错误：
Error: Could not find or load main class class

应该是hbase的环境变量没有设置好。
