Subject [jira] [Created] (HADOOP-8263) Stringification of IPC calls not useful
Date Mon, 09 Apr 2012 23:07:19 GMT
Stringification of IPC calls not useful
---------------------------------------

                 Key: HADOOP-8263
                 URL: https://issues.apache.org/jira/browse/HADOOP-8263
             Project: Hadoop Common
          Issue Type: Bug
          Components: ipc
    Affects Versions: 2.0.0
            Reporter: Todd Lipcon
            Assignee: Todd Lipcon
            Priority: Minor


Since the Protobufification of Hadoop, the log messages on IPC exceptions on the server side
now read like:

12/04/09 16:04:06 INFO ipc.Server: IPC Server handler 9 on 8021, call org.apache.hadoop.ipc.ProtobufRpcEngine$RpcRequestWritable@7087e9bf
from 127.0.0.1:47989: error: org.apache.hadoop.ipc.StandbyException: Operation category READ
is not supported in state standby

The call should instead stringify the method name and the request protobuf (perhaps abbreviated
if it is longer than a few hundred chars)
