Subject [jira] [Updated] (HDFS-2575) DFSTestUtil may create empty files
Date Mon, 21 Nov 2011 07:48:53 GMT

     [ https://issues.apache.org/jira/browse/HDFS-2575?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Todd Lipcon updated HDFS-2575:
------------------------------

    Attachment: hdfs-2575.txt

trivial change to make the minSize be 1 byte. I think this should be fine for all of the cases
I could find where we use this function. If we need to specify a different minSize later,
we can add a {{setMinSize}} function.

> DFSTestUtil creates files with random sizes, but there is no minimum size. So, sometimes,
it can make a file with length 0. This will cause tests that use this functionality to fail
- for example, TestListCorruptFileBlocks assumes that each of the created files has at least
one block. We should add a minSize parameter to prevent this.
