> -----------------------------------------------------
>
> Key: PHOENIX-5705
> URL: https://issues.apache.org/jira/browse/PHOENIX-5705
> Project: Phoenix
> Issue Type: Bug
> Affects Versions: 4.14.3
> Reporter: Priyank Porwal
> Assignee: Tanuj Khurana
> Priority: Major
> Fix For: 4.15.1, 4.14.4, 4.16.0
>
>
> It seems every few ms, the following cells are being rewritten without any
> change in values - PENDING_DISABLE_COUNT,
> INDEX_STATE,INDEX_DISABLE_TIMESTAMP,ASYNC_REBUILD_TIMESTAMP,_0
> Sometimes the rewrites have the same cell timestamps as well.
> These cells are all relevant to secondary indexes to it is likely that
> automated index rebuild system or Phoenix MR job submitter has an issue. This
> is true even if the index state is Active 'a'.
>
> REPRO:
> scan 'SYSTEM.CATALOG',
> {LIMIT=>1,RAW=>true,VERSIONS=>10,STARTROW=>"<syscatrowkey>"
> Get syscatrowkey:
> SELECT ROWKEY_BYTES_STRING() FROM SYSTEM.CATALOG WHERE COLUMN_NAME IS NULL
> AND DATA_TABLE_NAME IS NOT NULL AND TABLE_NAME = "<index_name>"
