Subject [jira] [Commented] (HDFS-2505) Add a test to verify getFileChecksum works with ViewFS
Date Thu, 05 Apr 2012 17:54:30 GMT

    [ https://issues.apache.org/jira/browse/HDFS-2505?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13247429#comment-13247429
] 

Tsz Wo (Nicholas), SZE commented on HDFS-2505:
----------------------------------------------

- The toString() below should be removed.
{code}
+    ConfigUtil.addLink(conf, "/tmp", new URI(fHdfs.getUri().toString() + "/tmp"));
{code}
Also, how about use different names for "/tmp", say "/hdfstmp" and "/viewfstmp"?

- Instead of checking null, how about get a file checksum from DistributedFileSystem for the
same file and then check equality?

> Please refer to HADOOP-7770. getFileChecksum was failing on files such as /tmp/someFile,
but working fine for /someDir/someFile.
> The fix is in HADOOP-7770 but we should have a test in HDFS which checks this functionality
(this test will fail until HADOOP-7770 is checked in)
