-------------------------------
Resolution: Not A Problem
> COMPUTE INCREMENTAL STATS with partition specs fails if no partition found
> --------------------------------------------------------------------------
>
> Key: IMPALA-6234
> URL: https://issues.apache.org/jira/browse/IMPALA-6234
> Project: IMPALA
> Issue Type: Bug
> Components: Frontend
> Affects Versions: Impala 2.8.0, Impala 2.9.0, Impala 2.10.0
> Environment: Impala-Shell: v2.8.0-cdh5.11.1 (3382c1c)
> Linux 2.6.32-504.8.1.el6.x86_64 Centos 6
> Impala JDBC: 2.5.29
> Reporter: Antoni Ivanov
> Assignee: Yongzhi Chen
> Priority: Major
> Labels: newbie
>
> I noticed that if no partition matches the "query" the compute stats fails
> (and hangs it doesn't get clean up):
> E.g COMPUTE INCREMENTAL STATS `foo` PARTITION (partition_column !=
> partition_column) - no partition would be matched
> returns the following error:
> AnalysisException: Syntax error in line 1:
> ...M history.astro_ui WHERE () GROUP BY pa__arrival_day, ...
> ^
> Encountered: )
> Expected: CASE, CAST, DEFAULT, EXISTS, FALSE, IF, INTERVAL, NOT, NULL,
> REPLACE, SELECT, TRUNCATE, TRUE, VALUES, WITH, IDENTIFIER
> CAUSED BY: Exception: Syntax error
> Also when using JDBC Impala Driver the query hangs until the connection is
> closed (and not just the statement) We are using Impala JBDC version 2.5.29.
> The query is in state "waiting to be closed" (as seen in Impala Deamon Web UI)
> Note that this behaviour happens only for COMPUTE INCREMENTAL STATS and not
> for DROP INCREMENTAL STATS. DROP finishes successfully with no issues.
