-------------------------------------
[~ashutoshc] , do you have any insight on this?
> alter partition should check for "hive.stats.autogather" in hiveConf
> --------------------------------------------------------------------
>
> Key: HIVE-8955
> URL: https://issues.apache.org/jira/browse/HIVE-8955
> Project: Hive
> Issue Type: Improvement
> Components: Metastore
> Affects Versions: 0.13.1
> Reporter: Pankit Thapar
> Fix For: 0.15.0
>
>
> When alter partition code path is triggered, it should check for the flag
> "hive.stats.autogather", if it is true, then only updateStats else skip them.
> This is done in append_partition code flow.
> Is there any specific reason the alter_partition does not respect this conf
> variable?
> //code snippet : HiveMetastore.java
> private Partition append_partition_common(RawStore ms, String dbName, String
> tableName,
> List<String> part_vals, EnvironmentContext envContext) throws
> InvalidObjectException,
> AlreadyExistsException, MetaException {
> ...
> ....
> if (HiveConf.getBoolVar(hiveConf,
> HiveConf.ConfVars.HIVESTATSAUTOGATHER) &&
> !MetaStoreUtils.isView(tbl)) {
> MetaStoreUtils.updatePartitionStatsFast(part, wh, madeDir);
> }
> ...
> ...
> }
> The above code snippet checks for the variable but this same check is absent
> in
> //code snippet : HiveAlterHandler.java
> public Partition alterPartition(final RawStore msdb, Warehouse wh, final
> String dbname,
> final String name, final List<String> part_vals, final Partition
> new_part)
> throws InvalidOperationException, InvalidObjectException,
> AlreadyExistsException,
> MetaException {
> ....
> ...
> }
