Subject Re: [VOTE] Apache Spark 3.0.0 RC1
Date Fri, 03 Apr 2020 15:49:40 GMT
Aside from the other issues mentioned here, which probably do require
another RC, this looks pretty good to me.

I built on Ubuntu 19 and ran with Java 11, -Pspark-ganglia-lgpl
-Pkinesis-asl -Phadoop-3.2 -Phive-2.3 -Pyarn -Pmesos -Pkubernetes
-Phive-thriftserver -Djava.version=11

I did see the following test failures, but as usual, I'm not sure
whether it's specific to me. Anyone else see these, particularly the R
warnings?
