hbase.client.RpcRetryingCaller Call exception

1. 环境 Environment

hbase client on mac, hbase server 1.2.2 on linux (ubuntu 16, jdk8).

2. 问题 problem

2017-11-26 09:25:52.074  INFO 16919 --- [hared--pool2-t5] o.a.h.hbase.client.RpcRetryingCaller     : Call exception, tries=10, retries=35, started=38477 ms ago, cancelled=false, msg=derekcheung-ThinkPad-X220 row 'users,TheRealMT,99999999999999' on table 'hbase:meta' at region=hbase:meta,,1.1588230740, hostname=derekcheung-thinkpad-x220,39702,1511653315036, seqNum=0

3. 解决办法 analysis and solution

在hbase server log里, 可以看到client有连接并分配了session id, 但是client put总是不成功, 报上面的错.

hbase:meta用来查region server信息, 到hbase server去scan一下hbase:meta,发现对应的region server address是用机器名表示的, 

问题就在于client拿到这个机器名后会找不到region server, 因为不知道ip嘛.

那么我们就要在hbase server和hbase client的机器上配置hosts, 把region server机器名map为真实的region server ip.
