[jira] [Commented] (HDFS-13148) Unit test for EZ with KMS and
Federation
[ https://issues.apache.org/jira/browse/HDFS-13148?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16441639#comment-16441639 ]
Xiao Chen commented on HDFS-13148:
----------------------------------
Thanks [~hanishakoneru] for working on this and Xiaoyu / Rushabh for reviews.
What is the goal of the improved testing? It seems we're trying make sure if there are 2 HDFS clusters with the same KMS, they will each work correctly. Although in theory KMS isn't impacted by HDFS, I agree having a test to cover it is nice.
I think a more interesting test is with viewfs: have a federated cluster, and make sure all [CryptoAdmin CLIs|http://hadoop.apache.org/docs/r3.0.0/hadoop-project-dist/hadoop-hdfs/TransparentEncryption.html#crypto_command-line_interface] work as expected. For example, does -listZones return a union of the 2 clusters? (We may end up with less line of codes if this is covered as a new TestCryptoAdminCLIWithFederation class and the test case in xml, but don't feel strongly)

> It would be good to have some unit tests for testing KMS and EZ on a federated cluster. We can start with basic EZ operations. For example, create EZs on two namespaces with different keys using one KMS.
