Subject [jira] [Commented] (HDFS-1968) Enhance TestWriteRead to support File Append and Position Read
Date Wed, 01 Jun 2011 03:13:47 GMT

    [ https://issues.apache.org/jira/browse/HDFS-1968?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13041959#comment-13041959

John George commented on HDFS-1968:

This is a very useful test. It does seem to test a lot of corner cases related to flush and
"visible byte" reads. 
I do see that this test has a lot of capability, so most of my comments are more related to
utilizing that part. As for the code itself, I found the changes useful.

1. Since this test already has the capability to test position reads, can that also be enabled
as a separate @test? Especially since that was something that brought out HDFS-2021 and HDFS-1907.

2. Since it has the capability to do fc, could we also enable that as another @test?

3. Should the WR_NTIMES and WR_CHUNK_SIZE be increased to reflect the failed case of HDFS-2021
and HDFS-1907? We can make this JIRA a dependent of those and thus possibly avoid having any
test failures.
