Description

Currently we have the following code:

    desc.addCoprocessor(SlowMeCoproScanOperations.class.getName());
    HBaseTestingUtility.modifyTableSync(admin, desc);
    //sleep for sometime. Hope is that the regions are closed/opened before
    //the sleep returns. TODO: do this better
    Thread.sleep(30000);

Instead of sleeping for fixed duration, we should detect when the regions have reopened with custom Coprocessor.
