[jira] [Commented] (YARN-4961) Wrapper for leveldb DB to aid in
handling database exceptions
[ https://issues.apache.org/jira/browse/YARN-4961?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16607520#comment-16607520 ]
Pradeep Ambati commented on YARN-4961:
--------------------------------------
[~jlowe], I want to work on this JIRA. From what I understood, there should be a utility wrapper around DB which throws IOExceptions (translated from DBExceptions) instead of DBExceptions, am I right?

> 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.
