Subject [jira] [Created] (HADOOP-10775) Shell operations could fail with meaningful errors on windows if winutils.exe not found
Date Wed, 02 Jul 2014 13:18:24 GMT
Steve Loughran created HADOOP-10775:
---------------------------------------

             Summary: Shell operations could fail with meaningful errors on windows if winutils.exe
not found
                 Key: HADOOP-10775
                 URL: https://issues.apache.org/jira/browse/HADOOP-10775
             Project: Hadoop Common
          Issue Type: Improvement
          Components: util
    Affects Versions: trunk-win
         Environment: Apache jenkins windows1 server
            Reporter: Steve Loughran
            Priority: Minor


If {{winutils.exe}} can't be found {{HADOOP_HOME}} wrong/unset or other causes, then an error
is logged -but when any of the {{Shell}} operations are used, an NPE is raised rather than
something meaningful.

The error message at setup time should be preserved and then raised before any attempt to
invoke a winutils-driven process made
