Tim Armstrong resolved IMPALA-1161.
-----------------------------------
Resolution: Cannot Reproduce
Query lifecycle has changed a lot since this, I'll close it since it's probably
been fixed.
> Hive Server 2 error log gives inconsistent results on backend progress
> ----------------------------------------------------------------------
>
> Key: IMPALA-1161
> URL: https://issues.apache.org/jira/browse/IMPALA-1161
> Project: IMPALA
> Issue Type: Bug
> Components: Distributed Exec
> Affects Versions: Impala 1.4
> Reporter: Abdullah Yousufi
> Priority: Minor
>
> There appears to be some lag between a query's execution and its log results.
> For example, running the same select query for a certain table sometimes
> accurately returns '100% Complete (3 out of 3),' but it might also return a
> partial completion, such as '66% Complete (2 out of 3)' or '33% Complete (1
> out of 3),' even though the results are complete each time.
> Impyla's implementation of execute is synchronous, so it waits until the
> query's execution status is in the finish state. Retrieving the error log
> after this point gives inconsistent backend progress results, though waiting
> a second before fetching the log or retrieving the error log a bit later,
> such as after fetching the results, fixes (or perhaps masks) the issue.
> This issue also occurs in Hue.
> This is also difficult to reproduce, though I've found creating a table with
> 10 to 30 rows and continuously fetching all rows generally results in the
> issue.
