-------------------------------------------
Summary: Use a client property for SaslConnection MAX_ATTEMPTS
(currently hardcoded to 5)
Key: HBASE-24499
URL: https://issues.apache.org/jira/browse/HBASE-24499
Project: HBase
Issue Type: Bug
Components: Client
Affects Versions: 1.3.2
Reporter: Ravi Kishore Valeti
Assignee: Ravi Kishore Valeti
Fix For: 2.3.0, master, 1.3.7
The no.of retries for Sasl handshake is hardcoded to 5 (MAX_ATTEMPTS). Use
cases which have strict SLAs on their operation timeouts need this to be
configurable to meet their SLAs.
Sample Scenario:
* RS is slow in accepting connections but is slow in responding to requests.
* Client makes a Sasl Connection attempt but times out on read (can be
configurable via hbase.ipc.client.socket.timeout.read) and retries 5 times at
this time (this is not configurable) and eventually bails out.
Make this configurable by a new client property (say
*hbase.security.relogin.maxretries)* so that clients/usecases can override and
meet their timeout SLAs.
