> Now that hdfs snapshots are here, we started to run our mapreduce jobs over
> hdfs snapshots. The thing is, hdfs snapshots are read-only point-in-time
> copies of the file system. Thus we had to modify the section of code that
> initialized the region internals in HRegion. We have to skip cleanup of
> certain directories if the HRegion is backed by a hdfs snapshot. I have a
> patch for trunk with some basic tests if folks are interested.
