In Phoenix4.0, global secondary index will be disabled when index update fails because the
data integrity between data & index has to been maintained.

You can manually reenable the index by using alter index to rebuild the index  OR upgrade
to the latest version(PHOENIX-950 improves this situation a little bit). In addition, local
secondary index, which in many cases are better than the global one,  is supported since 4.2

Subject: Phoenix Index Disabled

Hi,

Been stuck on this issue for few hours. Hoping someone can shed some light.

OS: Centos-6
Phoenix Client: phoenix-4.0.0.2.1.5.0-695-client.jar
Phoenix Core: phoenix-core-4.0.0.2.1.5.0-695.jar
Hbase Version: Version 0.98.0.2.1.5.0-695-hadoop2, 6 RS
Hbase RS Java Heap : 6 Gb

So,

1) Created a 1 column family, 6 column Phoenix table
2) Have an app that is continually streaming  data into the new Phoenix table
3) Created a Phoenix index on two of the columns of the new Phoenix.
4) Compare newly created Phoenix index count to row count in Hbase. They agree.
5) Wait a few minutes, do another comparison between Phoenix index count and Hbase row count.
Row count properly increments, but Phoenix index count shows same value.
6) Wait some more and get exact same outcome as in #5.
7) Check a RS log file, and see that the Phoenix index is "DISABLED" because it can not write
to a particular region.

OK.. what would cause the Phoenix index to become "DISABLED", especially since there were
no issues during index creation? Is there a configuration variable that needs to be modified?
Is there a suitable workaround beside developing a bash script to alter the index and rebuild.


Thanks
