> Had an odd situation where the monitor would throw an NPE constantly when I tried to
view any page.
> It was throwing a NPE trying to accessed the cached instance name. It appears that {{HdfsZooInstance.getInstance().getInstanceName(}}
may return null, but the monitor code is not written to account for that.
> The monitor should check for null values before setting the instance name into {{cachedInstanceName}}.
When the instance name is null, it should reschedule the timertask to try to fetch a (non-null)
instance name.
