[jira] [Created] (SQOOP-2905) Improve documentation for Oracle connector

Miklos Szurap created SQOOP-2905:
------------------------------------

             Summary: Improve documentation for Oracle connector
                 Key: SQOOP-2905
                 URL: https://issues.apache.org/jira/browse/SQOOP-2905
             Project: Sqoop
          Issue Type: Task
          Components: connectors/oracle
    Affects Versions: 1.4.6
            Reporter: Miklos Szurap


In the Sqoop user guide [1] there is a section for how to handle "java.net.SocketException: Connection reset" errors.

This needs to be improved because the Sqoop client itself can suffer from this error message, not only the mappers.

The solution is to specify a system property to the sqoop client too, thus the sqoop command will look like (for example to a sqoop import):

sqoop import -Djava.security.egd="file:///dev/../dev/urandom" -D mapreduce.map.java.opts="-Djava.security.egd=file:///dev/../dev/urandom" <other_sqoop_arguments>
