EndOfStreamException: Unable to read additional data from client sessionid 0x0, likely client has cl

今天在hbase中执行下面的命令

disable 'iw:test06'
    alter 'iw:test06',NAME=>'i',COMPRESSION=>'SNAPPY'
    count 'iw:test06'

提示下面的异常信息

2018-01-15 10:49:20,660 [myid:2] - INFO  [NIOServerCxn.Factory:0.0.0.0/0.0.0.0:2181:NIOServerCnxn@1008] - Closed socket connection for client /192.168.5.172:29409 (no session established for client)

执行命令`netstat -antp | grep 2181`,可以看到

参考[Hadoop 2.x常用端口及查看方法][Hadoop 2.x]查看端口使用情况  
在这篇文章[Hadoop及HBase使用过程中的一些问题集][Hadoop_HBase]中描述hb下面的regionserver全部掉线，其实不是zk的原因，而是hdfs的问题。  
[ Unable to read additional data from client sessionid 0x0, likely client has closed socket][Unable to read additional data from client sessionid 0x0_ likely client has closed socket]这篇文章解释需要配置`zookeeper.session.timeout.ms`,而zookeeper中minSessionTimeout与maxSessionTimeout是tickTime的2倍和20倍。看来问题不在于此。  
在`http://192.168.5.174:16010/master-status`中可以看到压缩后，原来Online Regions，现在变成了failed Regions.

继续跟进hbase的日志

网上一搜，很多原因会造成这个问题，这里整理一下，虽然没有解决我遇到的问题  
[hbase Master节点变更][hbase Master]  
[zookeeper或数据损坏][zookeeper]  
于是我按照下面的的步骤,参考[shut down ZM and HBase ][shut down ZM and HBase]

cp /home/hadoop/platform/zookeeper/data/myid /home/hadoop/bak/
    stop-dfs.sh
    stop-yarn.sh
    zkServer.sh stop
    stop-hbase.sh
    rm -Rf /home/hadoop/platform/zookeeper/data/*
    cp /home/hadoop/bak/myid  /home/hadoop/platform/zookeeper/data/ 
    start-dfs.sh
    start-yarn.sh
    zkServer.sh start
    start-hbase.sh

zookeeper的异常不见了。  
执行下面命令格式化查看zookeeper的日志

java -classpath .:/home/hadoop/application/zookeeper/lib/slf4j-api-1.6.1.jar:/home/hadoop/application/zookeeper/zookeeper-3.4.8.jar org.apache.zookeeper.server.LogFormatter /home/hadoop/platform/zookeeper/log/version-2/log.2f00000001
