Subject [jira] [Commented] (HADOOP-9905) remove dependency of zookeeper for hadoop-client
Date Wed, 05 Feb 2014 17:30:12 GMT

Steve Loughran commented on HADOOP-9905:
----------------------------------------

Alejandro, I'm still up for dropping the dependency on ZK

We can't have a "no changes to POMs or dependencies in Hadoop 2" policy. To do so says "we
can't ever upgrade any POM we depend on, in case transient dependencies change"

# we explicitly say "no guarantees about dependencies" in the compatibility document. That
was not an accident.
# this only affects downstream apps that work via maven, not production code
# we can mark it as 'incompatible" in the changes.

The patch isn't ready -yet- as we need to make sure YARN is up with it. But otherwise, I will
eventually +1 a patch that drops ZK from hadoop-cliient
