Subject [jira] [Commented] (HDFS-7625) TestPersistBlocks hardcode block size without considering native OS
Date Fri, 16 Jan 2015 08:34:36 GMT

    [ https://issues.apache.org/jira/browse/HDFS-7625?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14279980#comment-14279980

sam liu commented on HDFS-7625:
-------------------------------

The failure of TestBalancer should not be caused by the patch, because TestBalancer does not
invoke any API of current test TestPersistBlocks.
In my test env, TestBalancer passed with applying current patch.

> TestPersistBlocks hardcode block size with 'BLOCK_SIZE = 4096', however it's incorrect
on some platforms. For example, on power platform, the correct value is 65536.
