[jira] Issue Comment Edited: (HADOOP-5895) Log message shows -ve number of bytes to be merged in the final merge pass when there are no intermediate merges and merge factor is > number of segments

    [ https://issues.apache.org/jira/browse/HADOOP-5895?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12711990#action_12711990 ]

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

In computeBytesInMerges, getPassFactor() can return factor > number of segments and even though n++ is done based on condition includeFinalMerge, that is not good enough for the while loop to be executed.

Attaching patch with the fix. Please review and provide your comments.
