Subject [jira] [Created] (HADOOP-8795) BASH tab completion doesn't look in PATH, assumes path to executable is specified
Date Thu, 13 Sep 2012 00:45:08 GMT
Sean Mackrory created HADOOP-8795:
-------------------------------------

             Summary: BASH tab completion doesn't look in PATH, assumes path to executable
is specified
                 Key: HADOOP-8795
                 URL: https://issues.apache.org/jira/browse/HADOOP-8795
             Project: Hadoop Common
          Issue Type: Bug
            Reporter: Sean Mackrory
         Attachments: HADOOP-8795.patch

bash-tab-completion/hadoop.sh checks that the first token in the command is an existing, executable
file - which assumes that the path to the hadoop executable is specified (or that it's in
the working directory). If the executable is somewhere else in PATH, tab completion will not
work.

I propose that the first token be passed through 'which' so that any executables in the path
also get detected. I've tested that this technique will work in the event that relative and
absolute paths are used as well.
