Hi,
I got this error message:
15/03/03 10:22:41 ERROR OneForOneBlockFetcher: Failed while starting block

And then for the same index file and executor, I got the following errors
multiple times

What's the problem?
BTW, I'm using Spark 1.2.1-SNAPSHOT I built around Dec. 20. Is there any
bug fixes related to shuffle block fetching or index files after that?
Thanks,
