Jonathan Hsieh commented on HBASE-8352:
---------------------------------------
bq. You want doc and release notes? Or is either sufficient?
Good release notes is sufficient. We'll get it done here.
bq. Is there any way to make rolling upgrades work? Even making the snapshot
dir configurable would not allow for that.
I was thinking we need a "version lock" or "upgrade lock" to block certain
operations while rolling upgrades or rolling restarts for config changes are
happening. Out of scope here though.

> Testing HBase Snapshot on top of Hadoop's Snapshot branch
> (http://svn.apache.org/viewvc/hadoop/common/branches/HDFS-2802/), we found
> that both features used '.snapshot' directory to store metadata.
> HDFS (built from HDFS-2802 branch) doesn't allow paths with .snapshot as a
> component
> From discussion on [email protected], (see
> http://search-hadoop.com/m/kY6C3cXMs51), consensus was to rename '.snapshot'
> directory in HBase so that both features can co-exist smoothly.
