在create table的时候出现例如以下问题
1. ERROR: java.io.IOException: Table Namespace Manager not ready yet, try again later
解决方式：这个问题是从单机配置到多机配置的时候出的问题，改动conf/hbase-env.sh 凝视掉export HBASE_MANAGES_ZK=true
2. java.net.SocketTimeoutException: Call to datanode1/172.16.0.122:60020 failed because java.net.SocketTimeoutException: 60000 millis timeout while waiting for channel to be ready for read. ch : java.nio.channels.SocketChannel[connected local=/172.16.0.126:55277
remote=datanode1/172.16.0.122:60020]
问题: 主server和从server上hbase-site.xml中，zookeeper.session.timeout配置的时间不一致
解决方式：把主server和从server上hbase-site.xml中的zookeeper.session.timeout配置一致，统一成120000
3. RegionServer not running

问题:/etc/hosts 中把主机名配置成了127.0.0.1
解决方式：把主机名配置成实际IP地址
