Subject [jira] Updated: (HADOOP-1648) Add contrib jars to general hadoop CLASSPATH
Date Tue, 24 Jul 2007 04:26:31 GMT

     [ https://issues.apache.org/jira/browse/HADOOP-1648?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel

stack updated HADOOP-1648:

    Status: In Progress  (was: Patch Available)

Putting aside for the moment as adding contrib jars will not be sufficent solving this item.
 Would also need to add contrib conf directories to CLASSPATH but, at least in hbase, the
conf directory location can be set with a hbase-particular environment variable (HBASE_CONF_DIR).
 Finding alternate contrib conf directories would require polluting the top level hadoop script
with contrib specifics.

> A mapreduce job that depends on any of the hadoop contrib jars  must bundle the contrib
jar into its job jar or copy the contrib jar to the lib dir across the cluster because hadoop
contribs are not on the general hadoop CLASSPATH.  It would be an improvement if such as the
included hbase mapreduce tasks did not require the running of this extra step.
