Chris Nauroth updated HADOOP-13203:
-----------------------------------
Hadoop Flags: Reviewed
+1 for patch 010, pending pre-commit. I'll also kick off another full test run
against S3.
bq. failure of TestS3AContractRootDir which went away when run standalone ...
some race conditions/consistency condition to look at there
If this was a run with both {{-Pparallel-tests}} and {{-Dtest=TestS3A*}}, then
it's probably the problem we discussed elsewhere that passing these arguments
would erroneously include {{TestS3AContractRootDir}} in the parallel testing
phase.
> S3a: Consider reducing the number of connection aborts by setting correct
> length in s3 request

> Currently file's "contentLength" is set as the "requestedStreamLen", when
> invoking S3AInputStream::reopen(). As a part of lazySeek(), sometimes the
> stream had to be closed and reopened. But lots of times the stream was closed
> with abort() causing the internal http connection to be unusable. This incurs
> lots of connection establishment cost in some jobs. It would be good to set
> the correct value for the stream length to avoid connection aborts.
> I will post the patch once aws tests passes in my machine.
