Subject [jira] [Resolved] (ACCUMULO-2918) TServers expect zookeeper to have parent nodes created
Date Tue, 17 Jun 2014 23:45:11 GMT


Josh Elser resolved ACCUMULO-2918.

    Resolution: Fixed

Ended up just inline'ing the creation of the parent ZK nodes since we have no other need to
introduce an upgrade path presently. It's a little ugly to embed this logic, but it saves
us the complexity in pushing an upgrade process for something so trivial.

Wrote a test to make sure the node creation is working as intended, and verified that a 1.6.1-SNAPSHOT
install being brought up with 1.7.0-SNAPSHOT libs fails without the change, and succeeds with
the change.

Thanks for the ticket, [~ecn].
