Hi,
when I update my hbase from 0.20.6 to 0.90, some error occur:
Below is logs on 167.6.5.13, because Meta table is served by this server, so
other regionservers want to connect this server to getRegionInfo, but got
some error:
2011-01-28 17:14:18,291 WARN org.apache.hadoop.ipc.HBaseServer: IPC Server
Responder, call getRegionInfo([B@15e43aec) from 167.6.5.11:34887: output
error

Responder, call getRegionInfo([B@3ad8672e) from 167.6.5.14:50735: output
error
This caused the server on 11 and 14 socket timeout and shutdown:

Now, my question is what's the cause of "output error" ?
Before the "output error" warning, there is an EOFException, is there any
relationship with this error?
