Jason Lowe commented on YARN-4961:
----------------------------------

This would be akin to what LeveldbIterator does for the leveldb iterators.

> It would be nice to have a utility wrapper around leveldb's DB to translate the raw runtime
DBExceptions into IOExceptions.  This would help make the code using leveldb easier to read
and less error-prone to allowing the runtime DBExceptions to escape and potentially terminate
the calling process.
