Thanks [~jojochuang] for the new patch. Could you explain why do we need 
{{newConf = new Configuration(false);}} instead of the default ctor?

Wei-Chiu Chuang commented on HADOOP-13638:
--

The tests failed because UserGroupInformation.setConfiguration(conf) sets a 
global variable, and each test has a client side configuration which is 
overwritten by it.

Need to find a way to avoid interference between client and server.

[jira] [Commented] (HADOOP-13638) KMS should set UGI's Configuration object properly

Here's what I did to verify the patch:

Configure a CDH Hadoop cluster using LdapGroupsMapping and KMS. The KMS ACL 
rule denies "group1" from decrypting the key. I added additional log at 
{{Groups#}} to print the class name of the GroupMapping resolution 
object. Subsequently, I started KMS and do a few operations in a HDFS 
encryption zone to observe the class name printed.

> 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.

+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.
