Subject Re: Giraph (1.1.0-SNAPSHOT and 1.0.0-RC3) unit tests fail
Date Tue, 01 Jul 2014 18:40:22 GMT
Yes, the failures around Accumulo in hadoop_2 profile are expected and nothing
to worry about. I should've probably mentioned it in my RC announcement email.
Sorry about that.

Any failures in hadoop_1 profile would be a reason to reconsider RC0.

Thanks,
Roman.

P.S. This is one of the reasons we're still running with hadoop_1 as a default
profile.
