-------------------------------------

             Summary: Roll the specified writer in HFileOutputFormat2
                 Key: HBASE-19432
                 URL: https://issues.apache.org/jira/browse/HBASE-19432
             Project: HBase
          Issue Type: Improvement
    Affects Versions: 3.0.0, 2.0.0-beta-1
            Reporter: Guangxu Cheng
            Assignee: Guangxu Cheng


{code}
	// If any of the HFiles for the column families has reached
	// maxsize, we need to roll all the writers
	if (wl != null && wl.written + length >= maxsize) {
	  this.rollRequested = true;
	}
{code}
If we always roll all the writers, a large number of small files will be generated in the multi family or multi table scene.
So we should only roll the specified writer which HFile has reached maxsize.
