Subject [jira] Updated: (HDFS-741) TestHFlush test doesn't seek() past previously written part of the file
Date Thu, 29 Oct 2009 00:03:02 GMT

     [ https://issues.apache.org/jira/browse/HDFS-741?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Konstantin Boudnik updated HDFS-741:
------------------------------------

    Attachment: HDFS-741.patch

This fixes the seek problem.

However, two testcases (writing cross block and checksum boundaries) are failing.
>From the sizes of a block and checksum is seems that I can't seek over block boundary
and it might be a limitation of the test... I'm not sure....

> TestHFlush test doesn't seek() past previously written part of the file

> As a part of the test scenario a file is being written, 10th of the total length in a
time. Then a reader is opened to read what has been just written and hflush'ed. However, it
always starts reading from the 0 position of the file and doesn't seek to the start of the
portion written last.
