> 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.
