Subject Re: [VOTE] The 1st hbase 0.94.19 release candidate is available for download
Date Fri, 25 Apr 2014 03:06:09 GMT
BTW, the integration test finished with 2 errors. Logs are below. Not
really sure if they are relevent errors or not. It was running on the 8
nodes cluster. I will re-run that over night on the 4 nodes cluster and see.
