Subject Re: Hadoop library version issues and conflict
Date Thu, 28 Jan 2016 20:19:07 GMT
I'm not sure about the solution here, but it would be nice to have much
newer dependencies of everything.  There are a host of issues with newer
libraries running in the same VM as hbase and hadoop.  Even the newer hbase
libraries are 3+ year old.
