Re: hedged read bug

Hi Chirs, I write one test case base on HDFS-6231 patch. You are right, no future is canceled. But I find the while loop in hedgedFetchBlockByteRange method execute 30,000 times. Please see hedged-read-test-case.patch in HDFS-6494 jira. I think that may be one problem. 2014-06-10 4:46 GMT+08:00

Lei: If you can attach the test code from your first email to HDFS-6494, that would help us know the scenario you were referring to. Cheers On Mon, Jun 9, 2014 at 12:06 PM, Chris Nauroth wrote: > Hi Lei, > > I just reviewed this code path on trunk again, and I couldn't find a > problem. It ap

Re: hedged read bug

Hi Lei, I just reviewed this code path on trunk again, and I couldn't find a problem. It appears to me that if one future fails, then the exception handling logic will allow the other future to proceed without canceling. Also, I haven't been able to reproduce the infinite loop that you reported

hadoop-2.5 - June end?

Folks, As you can see from the Roadmap wiki, it looks like several items are still a bit away from being ready. I think rather than wait for them, it will be useful to create an intermediate release (2.5) this month - I think ATS security is pretty close, so we can ship that. I'm thinking of
