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 Talat 2015-03-25 15:52 GMT+02:00 Jean-Marc Spaggiari <jean-m...@spaggiari.org>: > Also, which HBase version is it? > > 2015-03-25 9:47 GMT-04:00 ramkrishna vasudevan < > ramkrishna.s.vasude...@gmail.com>: > >> Can you see if there is any exception in the Regionserver logs? >> >> On Wed, Mar 25, 2015 at 2:17 PM, Talat Uyarer <ta...@uyarer.com> wrote: >> >> > Hi all, >> > >> > I try to use Prefix Filter on hbase shell.
