> 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.
