exception.
Agree with you.
However, I recorded that if a timeout occurs in an RPC call, TException is
still thrown, and the new implementation is still not the way we want it to be.
Do you have any ideas on this? Or we could refer to existing
[implementations](https://github.com/apache/iotdb/blob/master/cluster/src/main/java/org/apache/iotdb/cluster/server/member/RaftMember.java#L1377),
but I'm not sure whether just specifying `socketTimeoutException` is enough.
