------------------------------------
Summary: Make the statestore HA rpc's socket connection timeout
tunable
Key: IMPALA-13427
URL: https://issues.apache.org/jira/browse/IMPALA-13427
Project: IMPALA
Issue Type: Improvement
Components: Backend
Reporter: Wenzhe Zhou
Assignee: Wenzhe Zhou
In some deployment environment, unsuccessful socket connection attempts take
long time to return error if connTimeout of the socket is set as 0. This causes
a daemon to tie up in unsuccessful connection attempts during initialization if
its peer is not ready.
When statestored HA is enabled, statestoreds do HA hand shack to negotiate
active role during initialization. If two statestored are initialized serially,
the first statestored may tie up in unsuccessful connection attempts since
the second statestored is not started.
Currently socket connection timeout of Thrift RPC is always set as 0. To avoid
this issue, we need to make the statestore HA rpc's socket connection timeout
tunable.
