Subject [jira] [Commented] (HDFS-7630) TestConnCache hardcode block size without considering native OS
Date Fri, 16 Jan 2015 14:21:35 GMT

    [ https://issues.apache.org/jira/browse/HDFS-7630?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14280270#comment-14280270

sam liu commented on HDFS-7630:
-------------------------------

The failure of TestFileTruncate should not be caused by the patch, because:
- TestFileTruncate does not invoke any API of current test TestConnCache
- Actually, in my test env, TestFileTruncate also failed without applying any patch

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