-------------------------------------
Summary: Hadoop RPC Authentication problem with different user
locale
Key: HADOOP-11507
URL: https://issues.apache.org/jira/browse/HADOOP-11507
Project: Hadoop Common
Issue Type: Bug
Affects Versions: 2.5.2
Reporter: Talat UYARER
Priority: Minor
When I try to use hadoop mapreduce framework with Turkish locale that set
default mapreduce.map.java.opts and mapreduce.reduce.java.opts to
-Duser.language=tr. It throws exception.
After Long research, i found a little bug in
org.apache.hadoop.security.SaslPropertiesResolver line 68. default setting of
hadoop.rpc.protection is authentication. When i make locale Turkish
authentication parameter with toUpperCase become AUTHENTİCATİON. Please
attention to dotted big i. This is a Turkish letter. It is very similar big i,
it just have addition dot. :)
IMHO who-one use upper or lowercase method for settings, it should use
Locale.ENGLISH. I created a patch file. But I could not test it. I can not find
which tests should i run. If you show me, I will be glad.
BTW I think, Hadoop Tests should be run different locale.

p.s. Exception is generated by a Hive query. It can be generated by any map
reduce job.
