[jira] [Commented] (HBASE-6962) Upgrade hadoop 1 dependency to hadoop 1.1

    [ https://issues.apache.org/jira/browse/HBASE-6962?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13496718#comment-13496718 ] 

Varun Sharma commented on HBASE-6962:
-------------------------------------

Hey folks,

I saw the hadoop 1.1.0 release notes and wanted to check on the Hadoop 8230 in particular. I am looking to try 1.1 with hbase 0.94 so as to get the hdfs stale node patches into the system. However, I wanted to check on the sync/append changes. Does this change mean that hsync is enabled by default and is going to be used for HBase append operation instead of the previous hflush implementation ? From my understanding, this would be a performance cost (persisting to disk vs writing to OS buffers) ?

Thanks
Varun
