----------------------------------------------
The unit test failure hadoop.hbase.client.TestZKAsyncRegistry is unrelated to
the patch.

> As described in the doc (see HBASE-15531), we would like to start with user
> tables for favored nodes. This task ensures FN does not apply to system
> tables.
> System tables are in memory and won't benefit from favored nodes. Since we
> also maintain FN information for user regions in meta, it helps to keep
> implementation simpler by ignoring system tables for the first iterations.
