-------------------------------------
I'm +1
> The partitioning job output should be un-splitable
> --------------------------------------------------
>
> Key: HAMA-757
> URL: https://issues.apache.org/jira/browse/HAMA-757
> Project: Hama
> Issue Type: Bug
> Components: bsp core
> Affects Versions: 0.6.1
> Reporter: MaoYuan Xian
> Attachments: HAMA-757.patch
>
>
> When the output sequence files from partitioning job are large(bigger than
> two hdfs file block size), the second round of the job (using these sequence
> file as input) will start up more tasks than client want. Some times, this
> uncertainty make the job exceed the cluster slot capacity.
> In the real project, I implemented an new Inputformat which marked as
> un-splitable to solve the problem. Is there any better way?
