Subject [jira] [Created] (HAMA-531) Data re-partitioning in BSPJobClient
Date Fri, 09 Mar 2012 05:45:57 GMT
Data re-partitioning in BSPJobClient
------------------------------------

                 Key: HAMA-531
                 URL: https://issues.apache.org/jira/browse/HAMA-531
             Project: Hama
          Issue Type: Improvement
            Reporter: Edward J. Yoon


The re-partitioning the data is a very expensive operation. By the way, currently, we processes
read/write operations sequentially using HDFS api in BSPJobClient from client-side. This causes
potential too many open files error, contains HDFS overheads, and shows slow performance.

We have to find another way to re-partitioning data.
