Sean Busbey commented on HBASE-17988:
-------------------------------------
I tried out this on master and I still get a failure for get-active-master.rb:
{code}
hbase-2.0.0-SNAPSHOT busbey$ ./bin/hbase org.jruby.Main
bin/get-active-master.rb
SLF4J: Class path contains multiple SLF4J bindings.

NoMethodError: undefined method `getServerNameOrEmptyString' for

Looking at ZKUtil, 'getServerNameOrEmptyString' is private.
> get-active-master.rb and draining_servers.rb no longer work

> Key: HBASE-17988
> URL: https://issues.apache.org/jira/browse/HBASE-17988
> Project: HBase
> Issue Type: Bug
> Components: scripts
> Affects Versions: 2.0.0
> Reporter: Mike Drob
> Assignee: Chinmay Kulkarni
> Priority: Critical
> Fix For: 2.0.0, 1.4.0, 1.3.2, 1.1.11, 1.2.7

> Attachments: HBASE-17988.patch

>
> The scripts {{bin/get-active-master.rb}} and {{bin/draining_servers.rb}} no
> longer work on current master branch. Here is an example error message:
> {noformat}
> $ bin/hbase-jruby bin/get-active-master.rb
> NoMethodError: undefined method `masterAddressZNode' for
> #<Java::OrgApacheHadoopHbaseZookeeper::ZooKeeperWatcher:0x1b0e9707>
> <main> at bin/get-active-master.rb:35
> {noformat}
> My initial probing suggests that this is likely due to movement that happened
> in HBASE-16690. Perhaps instead of reworking the ruby, there is similar Java
> functionality already existing somewhere.
> Putting priority at critical since it's impossible to know whether users rely
> on the scripts.
