------------------------------------
Summary: Testing : log thread stacks when metastore fails to start
Key: HIVE-13491
URL: https://issues.apache.org/jira/browse/HIVE-13491
Project: Hive
Issue Type: Bug
Components: Test, Testing Infrastructure
Reporter: Thejas M Nair
Assignee: Thejas M Nair
Many tests are failing in ptest2 because metastore fails to startup in the
expected time.
There is not enough information to figure out why the metastore startup
failed/got hung in the hive.log file. Printing the thread dumps when that
happens would be useful.
The stack in test failure looks like this -
