Subject Re: [VOTE] Sixth release candidate for HBase 1.0.0 (RC5) is available. Please vote by Feb 19 2015
Date Tue, 17 Feb 2015 19:57:16 GMT
Hum. When I do that I get a warning saying that the key might not belong to
its owner... But  expect this waning, I'm able to validate the
hbase-1.0.0-bin.tar.gz file.

Thanks,

JM
