             Summary: Sqoop2: Attach a debugger to miniclusters
                 Key: HADOOP-10875
                 URL: https://issues.apache.org/jira/browse/HADOOP-10875
             Project: Hadoop Common
          Issue Type: Bug
            Reporter: Abraham Elmahrek


It would be nice to have a way to attach a debugger to the miniclusters: http://cargo.codehaus.org/Starting+and+stopping+a+container.

For tomcat, I needed to add the following to TomcatSqoopMiniCluster:
{code}
configuration.setProperty(GeneralPropertySet.JVMARGS, "\"-agentlib:jdwp=transport=dt_socket,server=y,suspend=y,address=5005\"");
{code}

There should also be a way to attach a debugger to the Yarn container.
