Subject Re: managing complexity of clean Jenkins builds
Date Wed, 23 Nov 2011 01:03:30 GMT
One way out of this dilemma is to release one build, 0.92-security

Part of the justification is that the underlying hadoop distro is secure.
The assumption is that 0.92-security build can adequately handle insecure
hbase operations.

This would simplify the release process a lot.

Cheers
