Subject [jira] [Commented] (ACCUMULO-1593) Looking up instanceName in ZK doesn't use consistent encoding
Date Mon, 02 Sep 2013 17:19:51 GMT


Mike Drob commented on ACCUMULO-1593:

Yea, the string v long decision should be a separate discussion. The patch looks good, but
there is one other scenario that I thought of.

Could this break compatibility when upgrading from 1.5? I'm reasonably confident that a UUID
serializes the same between ASCII, UTF-8, and CP1252. However, I have no idea what people
use for their instance names and maybe that deserves an extra check. Probably could be a separate
JIRA. [~ctubbsii], what do you think?

They should use UTF-8 explicitly, right now, they use the JVM default, which can differ between
JVM runs (even between Initialize and start-all).
