Metadata does not automatically refresh in v1.0. The "refresh" command is
required to do so for each impalad process/node.

We have Impala 1.0 installed in our environment along with CDH4.2.1. This
morning we saw that not all the nodes had their metadata refreshed
automatically for a new table. The table was introduced yesterday. Is there
a reason that this happened? Is there a way to find out why this happened?
I was also wondering why each node has its own separate metadata cache.
