REST server is leaking ZK connections in 0.90
---------------------------------------------

                 Key: HBASE-4684
                 URL: https://issues.apache.org/jira/browse/HBASE-4684
             Project: HBase
          Issue Type: Bug
    Affects Versions: 0.90.4
            Reporter: Jean-Daniel Cryans
            Priority: Critical
             Fix For: 0.90.5


As reported a month ago, http://search-hadoop.com/m/FD6gmKzrxY1, the REST server is leak ZK
connections. Upon investigation I see that TableResource.scanTransformAttrs creates a new
HBA per minute per table (when the server is getting requests) but never deletes the connection
created in there.

There are a bunch of other places where HBAs are created but not cleaned after like SchemaResource,
StorageClusterStatusResource, StorageClusterVersionResource, ExistsResource, etc. Those places
shouldn't be as leaky under normal circumstances tho.

Thanks to Jack Levin for bringing up this issue again when he tried to upgrade.
