Subject [jira] [Commented] (HIVE-9367) CombineFileInputFormatShim#getDirIndices is expensive
Date Wed, 14 Jan 2015 20:47:34 GMT


Xuefu Zhang commented on HIVE-9367:

Thanks for the explanation. This is a shim class, so we are okay. Patch looks good to me.
One note though, is that prune() method seems no longer needed. Could you remove it?

Looked into it and it seems to me we should be able to get rid of this method completely if
we can enhance CombineFileInputFormatShim a little.
