Andrew Purtell commented on HBASE-22377:
----------------------------------------
Will fix issue found by TestInterfaceAlign.
The new checkstyle warnings identify that Eclipse decided to convert a long
list of specific imports into a wildcard. I don't have obvious control over
this behavior, it's something the IDE did behind by back. Let me look for some
kind of setting. For the time being I can make manual edits.
The test failures in hbase-server look unrelated:

> Currently, to check the existence of a namespace, clients can use
> HBaseAdmin#getNamespaceDescriptor. eEventually on the server-side, this calls
> AccessController#preGetNamespaceDescriptor which tries to acquire ADMIN
> permissions for that namespace.
> We should have an API for clients to be able to check the existence of a
> namespace, without necessarily obtaining the namespace descriptor. Such an
> API would not require ADMIN permissions.
