Sushanth Sowmyan updated HIVE-6572:
-----------------------------------
Attachment: HIVE-6572.patch
Patch attached.
[~owen.omalley], could you please check this patch real quick?
[~rhbutani], I would like this patch to also be included in the hive-0.13
release, since it fixes some erroneous config usage introduced in the 0.13
timeframe, and we don't want to have a release with them, which might make this
behaviour something we have to support in the longer run.
> Use shimmed version of hadoop conf names for mapred.{min,max}.split.size{.*}

> Key: HIVE-6572
> URL: https://issues.apache.org/jira/browse/HIVE-6572
> Project: Hive
> Issue Type: Bug
> Affects Versions: 0.13.0, 0.14.0
> Reporter: Sushanth Sowmyan

>
> HadoopShims has a method to fetch config parameters by name so that they
> return the appropriate config param name for the appropriate hadoop version.
> We need to be consistent about using these versions.
> For eg:. mapred.min.split.size is deprecated with hadoop 2.x, and is instead
> called mapreduce.input.fileinputformat.split.minsize .
> Also, there is a bug in Hadoop20SShims and Hadoop20Shims that defines
> MAPREDMINSPLITSIZEPERNODE as mapred.min.split.size.per.rack and
> MAPREDMINSPLITSIZEPERRACK as mapred.min.split.size.per.node. This is wrong
> and confusing.
