[jira] Commented: (HBASE-1155) Verify that FSDataoutputStream.sync() works

["Jim Kellerman (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/HBASE-1155?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12670657#action_12670657 ] 

Jim Kellerman commented on HBASE-1155:
--------------------------------------

Simple testing using the test programs that I attached to HADOOP-4379,  would seem to indicate that the patch for 4379 works. However we need more testing in the HBase environment to verify that the patch is sufficient.

> In order to guarantee that an HLog sync() flushes the data to the HDFS, we will need to invoke FSDataOutputStream.sync() per HADOOP-4379.
> Currently, there is no access to the underlying FSDataOutputStream from SequenceFile.Writer, as it is a package private member.
