Siyao Meng reassigned HDDS-17312:
---------------------------------
Assignee: Siyao Meng
Description:
{{XceiverClientGrpc}} reads {{ozone.client.read.timeout}}, and
{{ECXceiverClientGrpc}} reads {{ozone.client.ec.grpc.write.timeout}}, with
{{getTimeDuration(..., TimeUnit.SECONDS)}}, and applies the result as the gRPC
deadline in seconds ({{withDeadlineAfter(timeout, TimeUnit.SECONDS)}}). A
sub-second value such as {{500ms}} becomes 0, so every request to the datanode
fails immediately with {{DEADLINE_EXCEEDED}}. A value like {{1500ms}} becomes
1s.
The short-circuit client and server ({{XceiverClientShortCircuit}},
{{XceiverServerDomainSocket}}) already read {{ozone.client.read.timeout}} in
milliseconds.
Proposal: keep the timeout in milliseconds and use it as the deadline in
milliseconds. A value without unit should still mean seconds for these two
keys, to stay compatible with existing configurations.
