[jira] [Created] (HADOOP-15360) Log some more helpful information
when catch RuntimeException or Error in IPC.Server
He Xiaoqiao created HADOOP-15360:
------------------------------------
Summary: Log some more helpful information when catch RuntimeException or Error in IPC.Server
Key: HADOOP-15360
URL: https://issues.apache.org/jira/browse/HADOOP-15360
Project: Hadoop Common
Issue Type: Improvement
Components: ipc
Reporter: He Xiaoqiao
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.
