Jimmy Xiang commented on HBASE-3909:
------------------------------------
@Stack, we don't have to poll fs to find changes. We can just put the
lastmodifieddate of the file in ZK. Once the last modified date is changed, we
can load the file again.
When a new regionserver joins a cluster, it should always try to check if any
configuration is changed based on the configuration file last modified
date, which is kind of the version number of the file.
