Subject RE: Enabling region replication on Phoenix metadata tables
Date Thu, 08 Sep 2016 18:42:07 GMT
I agree with Michael on enabling region replication for the SYSTEM.CATALOG table. But when
I tried enabling region replication, I was not able to bring the HBase cluster.  I am using
HBase 1.2.1 and Phoenix 4.7 (on Amazon EMR Platform)

Subject: Enabling region replication on Phoenix metadata tables

Is there any reason why it would be a bad idea to enable region replication on the Phoenix
metadata tables. Specifically, SYSTEM.CATALOG et al.

From everything I’m reading it seems like it would be a good idea. Those tables are a single
point of failure for Phoenix. If they aren’t up then no Phoenix connection can be made.
