ATTACHMENT ID: 12734898 - PreCommit-HIVE-TRUNK-Build
> Hybrid Hybrid Grace Hash Join : Don't allocate all hash table memory upfront
> ----------------------------------------------------------------------------
>
> Key: HIVE-10793
> URL: https://issues.apache.org/jira/browse/HIVE-10793
> Project: Hive
> Issue Type: Bug
> Components: Hive
> Affects Versions: 1.2.0
> Reporter: Mostafa Mokhtar
> Assignee: Mostafa Mokhtar
> Fix For: 1.2.1
>
> Attachments: HIVE-10793.1.patch, HIVE-10793.2.patch
>
>
> HybridHashTableContainer will allocate memory based on estimate, which means
> if the actual is less than the estimate the allocated memory won't be used.
> Number of partitions is calculated based on estimated data size
> {code}
> numPartitions = calcNumPartitions(memoryThreshold, estimatedTableSize,
> minNumParts, minWbSize,
> nwayConf);
> {code}
> Then based on number of partitions writeBufferSize is set
> {code}
> writeBufferSize = (int)(estimatedTableSize / numPartitions);
> {code}
> Each hash partition will allocate 1 WriteBuffer, with no further allocation
> if the estimate data size is correct.
> Suggested solution is to reduce writeBufferSize by a factor such that only X%
> of the memory is preallocated.
