Attila Magyar resolved TEZ-4271.
--------------------------------
Resolution: Won't Fix
Instead of limiting it on the TEZ side we'll increase the range in Hive as part
of HIVE-24715.
> Add config to limit desiredNumSplits
> ------------------------------------
>
> Key: TEZ-4271
> URL: https://issues.apache.org/jira/browse/TEZ-4271
> Project: Apache Tez
> Issue Type: Bug
> Reporter: Attila Magyar
> Assignee: Attila Magyar
> Priority: Major
>
> raThere are multiple config parameters (like tez.grouping.min/max-size,
> tez.grouping.by-length, tez.grouping.by-count,
> tez.grouping.node.local.only) that impacts the number of grouped input splits
> but there is no single property for setting an exact top limit on the desired
> count.
> In Hive the max number of buckets is 4095. During an insert overwrite each
> tasks writes its own bucket and when TEZ runs more than 4095 tasks Hive fails
> with a bucketId out of range exception.
>
> When "tez.grouping.by-count" is used then clamping the desiredNumSplits would
> be easy. However when "tez.grouping.by-length" is enabled (which is the
> default) clamping desiredNumSplits is not enough since TEZ might generate a
> few more splits than the desired.
> For example:
> * originalSplits: [10, 10, 10, 10, 10, 10, 10, 10, 10, 10] where the first 5
> is on node0 the other 5 is on node1.
> * desiredNumSplits: 4
> * Total size: 100
> * lengthPerGroup: 100 / 4 = 25
> * group0: [node0=>10, node0=>10]
> * group1: [node1=>10, node1=>10]
> * group2: [node0=>10, node0=>10]
> * group2: [node1=>10, node1=>10]
> * group4: default-rack=>[node0=>10, node1=>10]
>
> The lengthPerGroup prevents adding more than 2 splits into the group
> resulting 5 groups instead of the 4 desired.
>
> If 25 was rounded up to 30 (lengthPerGroup = ceil(25 / 10) * 10) it would
> generate 3. But we can't assume all splits have the same size (?)
> We might need to detect if groupedSplits.size() is greater than desired in
> the loop, and redistribute the remaining splits across the existing groups
> (either in a round robin fashion or by selecting the smallest), instead of
> creating new groups. This might cause existing groups to be converted
> rackLocal groups if the node locality of the remaining is different then
> locality of the existing groups.
> Or doing a second pass after groupedSplits is fully calculated and trying to
> merge existing groups. Either way this complicates the logic even further. At
> this point I'm not sure what would be the best. [~rajesh.balamohan],
> [~t3rmin4t0r] do you have any suggestions?
