Samarth Jain commented on PHOENIX-3496:
---------------------------------------
Any updates on this, [~rajeshbabu]? Having to disable the data table when
creating a local index on it too is a non-starter IMHO since we are essentially
asking for a downtime on a parent table to create an index on it. Would an
async mechanism like map reduce building the index encounter the same issue?
Maybe we should always create a local index through our map reduce
integration?. CC, [~gjacoby]
bq. So while building the local index we might open scanner on old region not
able see the column family.
Is that something that can be fixed?
FWIW, we are still seeing test failures which I believe are using the sync
fashion of creating local indexes.

> The test has been passing consistently on the "4.*-HBase-0.98" branches.
> However, it has been flapping pretty regularly on the master branch and the
> "4.*-HBase-1.1" branches.
> I ran the test locally a few number of times and it did flap. I did notice
> that in cases where it failed, the logs also had a RegionOpeningException.
> For example:
> {code}
> org.apache.hadoop.hbase.exceptions.RegionOpeningException: Region
> TEST_TABLET000060,\x07\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00,1479426366023.04f765e5d906bbd193b38a9f8c20e478.
