Ed Espino updated HAWQ-999:
---------------------------
Labels: (was: ToBeClosed)
> Log_error when file count is not in proportion to bucket number of hash table.
> ------------------------------------------------------------------------------
>
> Key: HAWQ-999
> URL: https://issues.apache.org/jira/browse/HAWQ-999
> Project: Apache HAWQ
> Issue Type: Improvement
> Components: Core
> Reporter: Hubert Zhang
> Assignee: Hubert Zhang
> Fix For: 2.1.0.0-incubating
>
>
> By definition, file count of a hash table should be equal to or a multiple of
> the bucket number of the table. So if mismatch happens, we should not treat
> it as hash table in data locality algorithm.
> The default behaviour should LOG_ERROR and tell the user "file count is not
> in proportion to bucket number for hash table with oid=XXXXX. Some data maybe
> lost, if you still want to continue the query, set GUC
> assign_randomly_for_mismatched_hash_table to true and try again."
> If GUC assign_randomly_for_mismatched_hash_table is on, the behaviour changed
> to treat the hash table as random table in data locality algorithm.
