Andrew Purtell commented on PHOENIX-4214:
-----------------------------------------
bq. And HBase 1.3+ supports replication of bulk loads, I believe.
Yes, but there is an accounting problem with that we would need to fix first
before relying on it. Not a big deal. See HBASE-18116
> Scans which write should not block region split or close

> Key: PHOENIX-4214
> URL: https://issues.apache.org/jira/browse/PHOENIX-4214
> Project: Phoenix
> Issue Type: Bug
> Affects Versions: 4.12.0
> Reporter: Vincent Poon
> Attachments: splitDuringUpsertSelect_wip.patch
>
>
> PHOENIX-3111 introduced a scan reference counter which is checked during
> region preSplit and preClose. However, a steady stream of UPSERT SELECT or
> DELETE can keep the count above 0 indefinitely, preventing or greatly
> delaying a region split or close.
> We should try to avoid starvation of the split / close request, and
> fail/reject queries where appropriate.
