Subject [jira] [Updated] (HDFS-6198) DataNode rolling upgrade does not correctly identify current block pool directory and replace with trash on Windows.
Date Mon, 07 Apr 2014 20:33:14 GMT

Chris Nauroth updated HDFS-6198:
--------------------------------

    Attachment: HDFS-6198.1.patch

This patch uses the platform-specific file path separator.  I've verified that {{TestDataNodeRollingUpgrade}}
passes on both Mac and Windows after this patch.

> For rolling upgrade, the DataNode uses a regex to identify the current block pool directory
and replace it with the equivalent trash directory.  This regex hard-codes '/' as the file
path separator, which doesn't work on Windows.
