This is a PR to send the fetch failure message back to Web UI.
Before:

After (Please ignore the meaning of exception, I threw it in the code directly because it's hard to simulate a fetch failure):

ah, "sealed" is usually only applied to traits, as case classes themselves are not supposed to be extended.

Already replaced sealed with private[storage]. Thank you.

I tested this patch out locally, and it appears that, sadly, the cause is actually not propagated correctly back to the driver. I think we can revert this to the prior Utils.exceptionString() way, that looks good in the UI.

I will revert to the Utils.exceptionString() way.
Looks Utils.exceptionString() does not handle the nested exceptions like this. It only outputs the outermost exception info. Is it intentional?

That is almost certainly not intentional. I think the method was introduced rather recently, and does not have many users right now. It should be fixed.

I will try to fix it in another PR.

zsxwing · 2014-11-03T05:19:21Z

New screenshots for current codes (I threw the exception in onBlockFetchSuccess directly to make up an error)
