Subject [jira] Created: (HADOOP-3151) Hod should have better error messages.
Date Tue, 01 Apr 2008 21:12:24 GMT
Hod should have better error messages.

                 Key: HADOOP-3151
                 URL: https://issues.apache.org/jira/browse/HADOOP-3151
             Project: Hadoop Core
          Issue Type: Bug
          Components: contrib/hod
            Reporter: Arkady Borkovsky

gsgw1037:/homes/arkady/CDSR> hod allocate -n 4 -d xx
error: bin/hod failed to start.
error: invalid 'clusterdir' specified in section hod (--hod.clusterdir): xx
error: 1 problem found.
Check your command line options and/or your configuration file /grid/0/kryptonite/hod/conf/hodrc

   * Directory 'xx' does not exist - the message shuold say "Non-existing directory" (or "directory
not found"), not "invalid"
   * checking the configuration file will not help, the advice is confusing
   * checking the command line options is the obvious thing to do -- the advise is unnecessary.

(2) when hod does not understand the command, it prints the whole help options message --
which clobbers the screen and is confusing. It should give a meaningful message -- and may
say "type hod help for more info"
