> Map failure attempts to delete reducer _temporary directory on multi-query
> pig query

> Key: HIVE-13756
> URL: https://issues.apache.org/jira/browse/HIVE-13756
> Project: Hive
> Issue Type: Bug
> Components: HCatalog
> Affects Versions: 1.2.1, 2.0.0
> Reporter: Chris Drome
> Assignee: Chris Drome
> Attachments: HIVE-13756-branch-1.patch, HIVE-13756.1-branch-1.patch,
> HIVE-13756.1.patch, HIVE-13756.patch
>
>
> A pig script, executed with multi-query enabled, that reads the source data
> and writes it as-is into TABLE_A as well as performing a group-by operation
> on the data which is written into TABLE_B can produce erroneous results if
> any map fails. This results in a single MR job that writes the map output to
> a scratch directory relative to TABLE_A and the reducer output to a scratch
> directory relative to TABLE_B.
> If one or more maps fail it will delete the attempt data relative to TABLE_A,
> but it also deletes the _temporary directory relative to TABLE_B. This has
> the unintended side-effect of preventing subsequent maps from committing
> their data. This means that any maps which successfully completed before the
> first map failure will have its data committed as expected, other maps not,
> resulting in an incomplete result set.
