Summary: Automatic Refresh of Metadata for Local Catalog after
Compaction
Key: IMPALA-11032
URL: https://issues.apache.org/jira/browse/IMPALA-11032
Project: IMPALA
Issue Type: Improvement
Components: Catalog
Reporter: Yu-Wen Lai
Assignee: Yu-Wen Lai
After Hive compaction for tables created in the Hive warehouse, queries(HIVE
ACID table) made in Impala possibly fail with a FileNotFoundException if a file
removed by the Hive cleaner.
In IMPALA-10801, we check latest compaction id before serving metadata from
Catalogd. However, coordinators don't take advantage of that. Coordinators have
local cache so we will have do the same compaction check for coordinator as
well.
