Subject [jira] [Commented] (PHOENIX-4370) Surface hbase metrics from perconnection to global metrics
Date Wed, 21 Mar 2018 18:17:00 GMT


Ethan Wang commented on PHOENIX-4370:

I noticed that Jenkins is SUCCESS in Phoenix-4.x-HBase-1.3 integration, but FAILURE at PreCommit-PHOENIX.
is this a release blocker? 

[~mujtabachohan] please advice
