stack updated HBASE-6928:
-------------------------
Attachment: 6928_attempted_fix.txt
I think issue is a clash between random column family name chosen by
testHFileLink and the substitute name the backing SchemaMetrics uses if no cf
supplied (can happen in tests).
Going to commit to see if this fixes issue.
I can't reproduce locally for whatever reason though I've run it a bunch.
> TestStoreFile sometimes fails with 'Column family prefix used twice'
