Description

IPC.Server#logException doesn't not print exception stack trace when catch RuntimeException or Error, for instance:

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

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.
