[jira] [Commented] (HADOOP-15360) Log some more helpful information
when catch RuntimeException or Error in IPC.Server
[ https://issues.apache.org/jira/browse/HADOOP-15360?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16425194#comment-16425194 ]

------------------------------------------
FYI the AIOOBE is most likely fixed by HDFS-11755 + HDFS-11445

> Key: HADOOP-15360
> URL: https://issues.apache.org/jira/browse/HADOOP-15360
> Project: Hadoop Common
> Issue Type: Improvement
> Components: ipc
> Reporter: He Xiaoqiao
> Priority: Major

> IPC.Server#logException doesn't not print exception stack trace when catch RuntimeException or Error, for instance:
> {code:java}
> 2018-03-28 21:52:25,385 WARN org.apache.hadoop.ipc.Server: IPC Server handler 17 on 8020, call org.apache.hadoop.hdfs.protocol.ClientProtocol.getFileInfo from *.*.*.*:59326 Call#46 Retry#0 java.lang.ArrayIndexOutOfBoundsException: 0
> {code}
> this log message is not friendly for debug. I think it is necessary to print more helpful message or full stack trace when the exception is RuntimeException or Error.
