Subject Re: Hbase PrefixFilter Problem
Date Wed, 25 Mar 2015 14:36:43 GMT
Hi,

I use HBase 0.98.6-cdh5.3.2.

Only one regionserver has some warn logs. like this:

2:31:29.312 PMWARNorg.apache.hadoop.ipc.RpcServer

RpcServer.respondercallId: 1456110 service: ClientService methodName:
Scan size: 24 connection: 192.168.0.10:47064: output error

2:31:29.313 PMWARNorg.apache.hadoop.ipc.RpcServer

B.defaultRpcServer.handler=24,queue=0,port=60020: caught a
ClosedChannelException, this means that the server was processing a
request but the client went away. The error message was: null
