Date Wed, 27 Mar 2013 00:05:15 GMT

    [ https://issues.apache.org/jira/browse/HDFS-4538?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13614712#comment-13614712

Todd Lipcon commented on HDFS-4538:
-----------------------------------

The patch looks good. Repeating my earlier question:

bq. Were you able to test this in a real cluster as well? (eg running a new client with the
legacy path turned on against an old server?)

> Some users might want to use the legacy block reader, because it is available on Windows,
whereas the secure solution has not yet been implemented there.  As described in the mailing
list discussion, let's enable this.
