------------------------------
Summary: Potential memory leak on REST server if state-full
scanner is not deleted
Key: HBASE-14827
URL: https://issues.apache.org/jira/browse/HBASE-14827
Project: HBase
Issue Type: Bug
Reporter: Duo Xu
Currently when people are using REST APIs to create state-full scanner, do scan
with scanner id and delete scanner. However, if the clients never call delete
scanner or if the clients are on cloud VMs and VMs get reboot before delete
requests are sent, the resources associated with the scanner will never be
released on the REST server, "hbase.client.scanner.timeout.period" will release
the resources on region server side though.
So this will cause memory leak on REST server in some cases.
