[jira] [Created] (IMPALA-11155) TotalTime counter of PHJ node seems incorrect
Quanlong Huang created IMPALA-11155:
---------------------------------------
Summary: TotalTime counter of PHJ node seems incorrect
Key: IMPALA-11155
URL: https://issues.apache.org/jira/browse/IMPALA-11155
Project: IMPALA
Issue Type: Bug
Reporter: Quanlong Huang
Attachments: buggy-total-time-profile.txt.gz
The "TotalTime" in the following part of a profile seems incorrect:
{code:java}
HASH_JOIN_NODE (id=15):
ExecOption: Probe Side Codegen Enabled, Join Build-Side Prepared Asynchronously
Node Lifecycle Event Timeline: 2s292ms
- Open Started: 1s188ms (1s188ms)
- Open Finished: 2s279ms (1s091ms)
- First Batch Requested: 2s279ms (15.382us)
- First Batch Returned: 2s279ms (66.111us)
- Last Batch Returned: 2s292ms (13.249ms)
- Closed: 2s292ms (62.139us)
- InactiveTotalTime: 0.000ns
- PeakMemoryUsage: 1.99 MB (2083072)
- ProbeRows: 24.51K (24514)
- ProbeRowsPartitioned: 0 (0)
- ProbeTime: 697.065us
- RowsReturned: 24.44K (24439)
- RowsReturnedRate: 22.34 K/sec
- TotalTime: 1s093ms{code}
It's 1s093ms which doesn't seem to match the node lifecycle timeline. In the timeline, OPEN takes 1s091ms and GETNEXT takes 13.249ms.
Uploaded the compressed profile for investigation.
