>
> Shutdown logic in GrpcOmTransport should not use awaitTermination() on each
> channel and use separate loop with periodic check of channel.isTerminated()
> with overall limit of 5s. With current logic in worst case scenario
> shutdown() can wait up to number_of_channels * 5s and shutdown channels
> sequentially.
> {code:java}
> public void shutdown() {
> for (Map.Entry<String, ManagedChannel> entry:channels.entrySet()) {
> ManagedChannel channel = entry.getValue();
> channel.shutdown();
> try {
> channel.awaitTermination(5, TimeUnit.SECONDS);
> } catch (Exception e) {
> LOG.error("failed to shutdown OzoneManagerServiceGrpc channel {} : {}",
> entry.getKey(), e); } }
> LOG.info("{}: stopped", CLIENT_NAME);
> }{code}
