-------------------------------------
Summary: Deadlock in CatalogServiceCatalog due to read lock
upgrade to a write lock
Key: IMPALA-14400
URL: https://issues.apache.org/jira/browse/IMPALA-14400
Project: IMPALA
Issue Type: Bug
Components: Catalog
Affects Versions: Impala 5.0.0
Reporter: Riza Suminto
Assignee: Riza Suminto
Attachments: jstack_dump.txt
test_metadata_after_failover_with_delayed_reset from a precommit jenkins job
caught a case where CatalogD hang with deadlock during startup.
This is easily hit when TRIGGER_RESET_METADATA_DELAY is increased to 3s. The
reason is, EventProcessor attempt to obtain versionLock_.writeLock() in
CatalogServiceCatalog.getDb() after obtaining versionLock_.readLock() in
CatalogServiceCatalog.getDbProperty() (unsafe lock upgrade from read to write).
[^jstack_dump.txt] shows the jstack when the deadlock occurs.
