Rajesh Balamohan commented on TEZ-4271:
---------------------------------------
"tez.grouping.by-count" is kind of experimental in nature and has not been
battle tested. Also, setting it to much higher value (e.g 4096) can have
adverse impact on other jobs, as it would bail out, when the original splits
are lesser than "desired split size". This can have undesired impact on jobs
when there is enough cluster capacity available.
There were other corner cases with columnar storage which caused skew in the
split sizes vs actual uncompressed data. This was the reason for introducing
TEZ-1993 (split estimator). Group by count tries to do a fair computation, but
it also depends on the incoming data.
[https://github.com/apache/tez/blob/master/tez-mapreduce/src/main/java/org/apache/tez/mapreduce/grouper/TezSplitGrouper.java#L374]
If the usecase has to really restrict split counts, it would be good to try
disabling "tez.grouping.by-length" along with "tez.grouping.by-count".
Another option could be to set "tez.grouping.by-count" (& related configs) as
corrective option from upstream and recompute the splits depending on the
usecase (i.e when the computed splits are much higher specific value e.g 4096).
> 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
>
> There 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?
