Subject [jira] [Reopened] (HADOOP-10538) NumberFormatException happened when hadoop 1.2.1 running on Cygwin
Date Thu, 24 Apr 2014 21:09:16 GMT

     [ https://issues.apache.org/jira/browse/HADOOP-10538?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Arpit Agarwal reopened HADOOP-10538:
------------------------------------


Never mind, I missed that this is Hadoop 1.2.1 although it is right there in the title.

I would recommend upgrading to Hadoop 2.4 unless you have a compelling reason to stick with
1.x. It is stable and works natively on Windows.
