Hello Dalia,

You might want to provide more details.

1) You are writing to the Hive mailing list. Does it means you want to run
a hive query?
The wiki is not exhaustive (and that's why you might want also to get the
"Programming Hive" book) but it is still a good start.

If your question is not Hive related, then for all general Hadoop
questions, there is the user@hadoop.apache.org mailling list. Hive is only
one way among others to query/manipulate data within a Hadoop cluster.

2) The distributed nature of Hadoop is not 'transparent'. You can not ask
it to execute any random java program is a ditributed wau  Do you already
have a job that you can launch?

3) Being on ubuntu and the way the cluster was installed might have a
slight impact on how to execute a hadoop job but it shouldn't be major.
Is there any particular point about launching a job which is not clear for
you? The documentation should be enough.
