Subject [jira] Resolved: (MAPREDUCE-2030) Throwing IOException while submitting the gridmix jobs consecutively through ToolRunner.
Date Tue, 31 Aug 2010 06:34:56 GMT

     [ https://issues.apache.org/jira/browse/MAPREDUCE-2030?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Amar Kamat resolved MAPREDUCE-2030.
-----------------------------------

    Resolution: Invalid

I have opened MAPREDUCE-2044 and MAPREDUCE-2045 to address this. '-' should be used only when
the input trace is expected via standard input (System.in).
