Aaron T. Myers updated HDFS-3444:
---------------------------------
Attachment: HDFS-3444.patch
Here's a patch which addresses the issue. The problem was: a) there was no
KerberosInfo annotation on the GetGroupsProtocolPB interface and b) the hdfs
get groups commands was not subbing in the NN server principal for the generic
GetGroups interface.
No tests are included since security is required to exercise this bug. I tested
it manually on a cluster with security enabled and confirmed that it works as
expected.
> hdfs groups command doesn't work with security enabled
