            你去看一下你的hbase-site.XML文件里面。
hbase.tmp.dir这配置，你是不是做了更改？
如果做了更改，用回/tmp/hbase-${user.name}这个。
        

            将hbase-site.XML
hbase.tmp.dir
/tmp/hbase-${user.name}
改成上述。
        

            楼主，你的问题解决了没有

这个问题和这个临时目录有关系吗
  如果设置成不更改这个目录会在重启的时候删除
        

            楼主的问题解决了没啊？
        

            使用独立的zookeeper解决
