[jira] [Commented] (HADOOP-13638) KMS should set UGI's
Configuration object properly
[ https://issues.apache.org/jira/browse/HADOOP-13638?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15511213#comment-15511213 ]

------------------------------------
+1 pending jenkins. Nice work Wei-Chiu!
This is clearly a bug and I think manual testing is fine. Could you elaborate a little bit on the manual testings you've done? Thanks.

> We found that the Configuration object in UGI in KMS server is not initialized properly, therefore it does not load core-site.xml from {{KMSConfiguration.KMS_CONFIG_DIR}}.
> This becomes a problem when the Hadoop cluster uses LdapGroupsMapping for group resolution, because the UGI in KMS falls back to the default JniBasedUnixGroupsMappingWithFallback (defined in core-default.xml) and is thus not consistent with the Hadoop cluster.
