Hi,
The stat() call in following code for connecting from Application Master to the Resource Manager is taking between 800 to 900 ms, tried with both managed and unmanaged applications.
AMRMClientAsync.CallbackHandler allocListener = new RMCallbackHandler();
amRMClient = AMRMClientAsync.createAMRMClientAsync(1000, allocListener);
amRMClient.init(conf);
amRMClient.start();
