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.
