Lars Hofhansl commented on PHOENIX-3407:
----------------------------------------
Thanks [~jamestaylor]. I think this warrants a 4.8.2 release in addition to
4.9.0.
> Read only RowLock may lead to corrupting SYSTEM.CATALOG and non atomic
> sequences in HBase 1.2

> We're taking a reentrant read lock when we should be taking a write lock in
> MetaDataEndPointImpl:
> {code}
> RowLock rowLock = region.getRowLock(key, true);
> {code}
> Not sure if the HBase API changed at some point, but I could have sworn the
> boolean was for whether or not you wanted to block.
