> Affects Versions: 2.0.4-alpha, 2.2.0
> Reporter: Sangjin Lee

>
> CombineFileInputFormat can easily create splits that can come from many
> different locations (during the last pass of creating "global" splits).
> However, we observe that this often runs afoul of the
> mapreduce.job.max.split.locations check that's done by JobSplitWriter.
> The default value for mapreduce.job.max.split.locations is 10, and with any
> decent size cluster, CombineFileInputFormat creates splits that are well
> above this limit.
