Nick Dimiduk commented on HBASE-18444:
--------------------------------------

What's the use-case for running multiple cluster instances from the same root dir? Seems like a Bad Idea(tm), at least without a forced read-only mode for region boundaries.

> This patch provides user an ability to have a custom meta table suffix.
> In order to share a common rootDir amongst multiple HBase clusters, we need separate meta table for each cluster.
> With custom meta table suffix, the meta table is named in the form of meta_{suffix} making it specific to a cluster.
> Users can specify the meta table suffix as part of hbase-site.xml.
