> ----------------------------------------------------------------
>
> Key: HIVE-17233
> URL: https://issues.apache.org/jira/browse/HIVE-17233
> Project: Hive
> Issue Type: Bug
> Components: HCatalog
> Affects Versions: 2.2.0, 3.0.0
> Reporter: Mithun Radhakrishnan
> Assignee: Mithun Radhakrishnan
> Attachments: HIVE-17233.1.patch
>
>
> This has to do with {{HIVE-15575}}. {{TezCompiler}} seems to set
> {{mapred.input.dir.recursive}} to {{true}}. This is acceptable for Hive jobs,
> since this allows Hive to consume its peculiar {{UNION ALL}} output, where
> the output of each relation is stored in a separate sub-directory of the
> output-dir.
> For such output to be readable through HCatalog (via Pig/HCatLoader),
> {{mapred.input.dir.recursive}} should be set from {{HCatInputFormat}} as
> well. Otherwise, one gets zero records for that input.
