Summary: Instrument catalog lock objects to dump diagnostics
Key: IMPALA-7958
URL: https://issues.apache.org/jira/browse/IMPALA-7958
Project: IMPALA
Issue Type: Improvement
Components: Catalog
Affects Versions: Impala 3.1.0
Reporter: bharath v
If a particular thread is holding a given lock for longer than X ms
(configurable), we should dump the following information to the logs.
- Thread stack of the thread holding the lock
- Thread stacks of the threads blocked on this lock.
We initially need to do this for the re-entrant table lock protecting
concurrent table updates. We can also do this for catalogVersionLock_ but we
don't anticipate much contention around it with v2 architecture.
The idea is to root cause Catalog hangs better, especially in the context of
concurrent table updates.
