> 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.
