Enis Soztutar commented on HBASE-13812:
---------------------------------------
bq. -1 core tests. The patch failed these unit tests:
bq. org.apache.hadoop.hbase.backup.TestHFileArchiving
I thought that this is a flaky test, but seems that the patch surfaced this.
I'll commit a quick addendum.
> Deleting of last Column Family of a table should not be allowed
