[jira] [Created] (KUDU-2925) ToolTest.TestLoadgenZeroRowsPerThread
didn't write to the WAL in time
Andrew Wong created KUDU-2925:
---------------------------------
Summary: ToolTest.TestLoadgenZeroRowsPerThread didn't write to the WAL in time
Key: KUDU-2925
URL: https://issues.apache.org/jira/browse/KUDU-2925
Project: Kudu
Issue Type: Improvement
Components: consensus, log, test
Affects Versions: 1.11.0
Reporter: Andrew Wong
Attachments: kudu-tool-test.3.txt.gz
I saw a run of ToolTest.TestLoadgenZeroRowsPerThread that failed because writing to the WAL took 90s. It's not clear why, or whether this was due to hardware issues or a deadlock somewhere.
