Subject [jira] [Updated] (HADOOP-11464) Reinstate support for launching Hadoop processes on Windows using Cygwin.
Date Tue, 06 Jan 2015 21:03:34 GMT

     [ https://issues.apache.org/jira/browse/HADOOP-11464?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel

Chris Nauroth updated HADOOP-11464:
    Attachment: HADOOP-11464.001.patch

I have attached patches for branch-2 and trunk.  For branch-2, this is just a matter of restoring
some old code that had existed previously.  For trunk, this is new code attempting to stick
more to the style of the new shell script rewrite.

I have tested this by running commands through all relevant entry (hadoop, hdfs, yarn and
mapreduce).  I ran HDFS commands, word count jobs, streaming jobs, created har files (to make
sure TOOL_PATH was covered), listed MR jobs and listed YARN applications.  This worked successfully
on Windows/Cygwin and Mac for both the trunk and branch-2 versions.

> The Windows compatibility work removed the dependency on Cygwin as a compatibility layer.
 However, some users may still wish to run Cygwin on a personal machine for running Hadoop
commands that interact with a cluster.  This issue proposes to reinstate support for launching
Hadoop processes on Windows using Cygwin to call the bash scripts.
