Subject Re: Introducing ConsensusNode and a Coordination Engine
Date Thu, 19 Jun 2014 03:45:56 GMT

In the last a couple of weeks, we had a very good and productive initial round
of discussions on the JIRAs. I think it is worthy to keep the momentum going
and have a more detailed conversation. For that, we'd like to host s Hadoop
developers meetup to get into the bowls of the consensus-based coordination
implementation for HDFS. The proposed venue is our office in San Ramon, CA.

Considering that it is already a mid week and the following one looks short
because of the holidays, how would the week of July 7th looks for yall?
Tuesday or Thursday look pretty good on our end.

Please chime in on your preference either here or reach of directly to me.
Once I have a few RSVPs I will setup an event on Eventbrite or similar.

Looking forward to your input. Regards,
