Íñigo Goiri commented on HDFS-14390:
------------------------------------
Thanks [~ashvin] for the patch.
The unit test failure is unrelated and present in many other builds.
The added test seems to work as expected;
https://builds.apache.org/job/PreCommit-HDFS-Build/26521/testReport/org.apache.hadoop.hdfs.server.aliasmap/TestSecureAliasMap/
A couple minor comments:
* Let's fix the javac warning.
* I probably would do the setup of the test as @Before and @After (without
statics).
* Can we use some of the utilities already present for security? For example
SecurityUtil or so.
Regarding the comment from [~virajith], I think that's a reasonable assumption.
Maybe we can check for that in the unit test for it to provide a reference?

> With {{PROVIDED}} storage (-HDFS-9806)-, HDFS can address data stored in
> external storage systems. This feature is not supported in a secure HDFS
> cluster. The {{AliasMap}} service does not support kerberos, and as a result
> the cluster nodes will fail to communicate with it. This JIRA is to enable
> kerberos support for the {{AliasMap}} service.
