Subject [jira] [Commented] (HDFS-7199) DFSOutputStream can silently drop data if DataStreamer crashes with a non-I/O exception
Date Thu, 30 Oct 2014 19:58:35 GMT

    [ https://issues.apache.org/jira/browse/HDFS-7199?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14190712#comment-14190712

Colin Patrick McCabe commented on HDFS-7199:
--------------------------------------------

The "else" should be on the same line as the close-brace, as per our coding standard.  +1
once that's fixed.  Thanks, Rushabh.

> If the DataStreamer thread encounters a non-I/O exception then it closes the output stream
but does not set lastException.  When the client later calls close on the output stream then
it will see the stream is already closed with lastException == null, mistakently think this
is a redundant close call, and fail to report any error to the client.
