We are using grpc client in hive which is a long running process, but seems there are many threads named grpc-default-worker-ELG won't close even if the task is done. How can I close these?

When you create NettyClientTransport what values are you passing for keepAliveTimeInNanos, keepAliveTimeoutInNanos and keepAliveWithoutCalls, especially the last one.

keepAliveWithoutCalls is false, also there are many file descriptor about eventfd, timerfd won't be released.
