Rajeshbabu Chintaguntla commented on PHOENIX-2575:
--------------------------------------------------
This is the reason for failure [[email protected]]. We are not supporting
getting last key on IndexHalfStoreFileReader because we don't know exact last
key for the daughter region. It's introduced after HBASE-14643. As part of
PHOENIX-2628 removing HFileScanner implementation and moving the logic to
StoreFileScanner. Now currently split's on local indexes won't work after
HBASE-14643.

> Project: Phoenix
> Issue Type: Bug
> Reporter: Samarth Jain
> Assignee: Rajeshbabu Chintaguntla
> Fix For: 4.8.0
>
> Attachments: PHOENIX-2575.patch
>
>
> On one of the test runs on 4.x-HBase-1.0, I see that the LocalIndexIT class
> didn't complete. Run -
> https://builds.apache.org/job/Phoenix-4.x-HBase-1.0/300/console. This is an
> attempt to prevent the indefinite hang by adding a timeout to count down
> latches.
