Subject [jira] [Commented] (ACCUMULO-1494) add a "run user jar" command to accumulo start script
Date Wed, 05 Jun 2013 17:18:20 GMT

    [ https://issues.apache.org/jira/browse/ACCUMULO-1494?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13676131#comment-13676131
] 

Sean Busbey commented on ACCUMULO-1494:
---------------------------------------

Two issues:

* a jar command makes it easier for new-comers familiar with hadoop to use accumulo
* just adding to the classloader doesn't allow the client jar provider to use the Manifest's
mainClass to ease integration

Other than that, updating the docs to suggest the use of the add argument would work.

> Rather than suggesting users run a client by adding their client jars to lib/ext (ref:
[1.4|http://accumulo.apache.org/1.4/user_manual/Writing_Accumulo_Clients.html], [1.5|http://accumulo.apache.org/1.5/accumulo_user_manual.html#_writing_accumulo_clients])
we should provide an equivalent to the [hadoop jar command|http://hadoop.apache.org/docs/stable/commands_manual.html#jar].

> Like the hadoop jar command, if the jar manifest defines a mainClass, it should use it.
Otherwise, it should use the command line provided one.
