Eric Yang updated YARN-8216:
----------------------------
Description:
System monitoring software usually send a tcp packet to test if port is alive.
This can cause RegistryDNS to throw BufferUnderflowException.
{code}
2018-04-26 17:07:55,846 WARN org.apache.hadoop.util.concurrent.ExecutorHelper:

This is perfectly normal, but it would be nice to hide this error message to
reduce verbose logging on port ping.
