---------------------------------------
Summary: SYSTEM.CATALOG rows are rewritten with high frequency
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
Fix For: 4.15.1, 4.14.4
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>"
