Subject [jira] Commented: (HADOOP-1622) Hadoop should provide a way to allow the user to specify jar file(s) the user job depends on
Date Thu, 19 Jul 2007 10:11:05 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-1622?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#action_12513862
] 

Enis Soztutar commented on HADOOP-1622:
---------------------------------------

> I'd also suggest to change bin/hadoop or the underliying java code to accept options
like --additionalJars
Adding such generic options can easily be achieved with the proposed implementation in HADOOP-1436.
We would parse the argument(s) in HadoopCommandLineParser, set some parameter to be the name
of the additional jar(s),  then change JobConf(Configuration) to respect that.

> More likely than not, a user's job may depend on multiple jars.
> Right now, when submitting a job through bin/hadoop, there is no way for the user to
specify that. 
> A walk around for that is to re-package all the dependent jars into a new jar or put
the dependent jar files in the lib dir of the new jar.
> This walk around causes unnecessary inconvenience to the user. Furthermore, if the user
does not own the main function 
> (like the case when the user uses Aggregate, or datajoin, streaming), the user has to
re-package those system jar files too.
> It is much desired that hadoop provides a clean and simple way for the user to specify
a list of dependent jar files at the time 
> of job submission. Someting like:
> bin/hadoop .... --depending_jars j1.jar:j2.jar
