> While writing a testcase for HBASE-62, I observed that table metadata is
> cached as part of the region information cached client side. This cached
> region information (and therefore table metadata) is not directly invalidated
> by disable/enable table, so to get up to date metadata the client may have to
> use a scanner over .META. directly using the meta visitor. Ideally other
> client code -- for example the support for HBASE-62 -- should be able to
> invalidate entries as necessary, so then the next HTable.getTableDescriptor()
> would go to meta to return up to date information instead of incorrectly
> reusing outdated information from the cache.
