Lars Volker updated IMPALA-5555: -------------------------------- Labels: observability supportability (was: supportability) > Add timeline event to query profile to indicate that it is finished > ------------------------------------------------------------------- > > Key: IMPALA-5555 > URL: https://issues.apache.org/jira/browse/IMPALA-5555 > Project: IMPALA > Issue Type: Bug > Components: Backend > Affects Versions: Impala 2.8.0 > Reporter: Jenny Kim > Priority: Major > Labels: observability, supportability > > Hue added a feature where after a user runs a query in Impala, we check the > Query Profile (from the ImpalaD Web UI) for the RowsProduced statistic (from > the Coordinator Fragment) and report that back as the total rows returned. > We're noticing that for some long running queries, the RowsProduced will be > incorrect (reporting 4 despite getting 198 rows) *right* after the query is > complete, but will be correct a few seconds later (validated by checking the > query profile manually). We discovered that by adding a latency of a few > seconds, we can usually get the correct RowsProduced. > But I was wondering if there's something smarter we can do, by checking > either a value in the query profile itself, or somewhere else. We tried > checking the hasResults value on the Thrift result handle as well as the > status of the operation handle, but unfortunately these don't seem to have > any effect (i.e. - they can be True or SUCCESSFUL even though the query > profile doesn't have the right RowsProduced number). > Can something be added to the Query Profile itself to indicate that the > RowsProduced is correct? -- This message was sent by Atlassian JIRA (v7.6.3#76005) --------------------------------------------------------------------- To unsubscribe, e-mail: issues-all-unsubscr...@impala.apache.org For additional commands, e-mail: issues-all-h...@impala.apache.org
