Andrew Purtell commented on HBASE-4684: --------------------------------------- Patch to fix the leak attached. Still not thrilled with scan/rescan of table attributes for transformation directives, in retrospect. Could do something like: {code} public class RESTConfiguration extends HBaseConfiguration { public RESTConfiguration() { super(); addResource("hbase-rest-site.xml"); } } {code} and get transform configuration from the configuration presumably as specified in the additional REST config file if it exists. More likely a REST gateway will be bounced than a table attribute changed? At least until online schema updates. > 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 > > Attachments: HBASE-4684-0.90.patch > > > 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. -- This message is automatically generated by JIRA.
