-------------------------------------
Summary: Able to write indexed value to data table without writing
to index table
Key: PHOENIX-5515
URL: https://issues.apache.org/jira/browse/PHOENIX-5515
Project: Phoenix
Issue Type: Bug
Affects Versions: 4.14.3
Reporter: Vincent Poon
Using the 4.14.3 client, it still seems the IndexFailurePolicy is still kicking
in, which disables the index on write failure. This means that while the index
is in 'disabled' state, writes to the data table can happen without any writes
to the index table. While in theory this might be ok since the rebuilder
should eventually kick in and rebuild from the disable_timestamp, this breaks
the new indexing design invariant that there should be no data table rows
without a corresponding index row (potentially unverified), so this could
potentially cause some unexpected behavior.
Steps to repro:
1) Create data table
2) Create index table
3) "close_region" on index region from hbase shell
4) Upsert to data table
Eventually after some number of retries, the index will get disabled, which
means any other client can write to the data table without writing to the index
table.
