------------------------------
Summary: LLAP: Tez heartbeats are delayed by ~500+ ms due to
Hadoop IPC client
Key: HIVE-10132
URL: https://issues.apache.org/jira/browse/HIVE-10132
Project: Hive
Issue Type: Sub-task
Reporter: Gopal V
HADOOP-11772 has a clearer bug report of the core issue inside hadoop-common.
Due to the delayed heartbeats reaching the AM, the reducers are losing up-to a
couple of seconds for a 60ms (x10 parallel) mapper + 300ms reducer instead of
finishing the query in under a second.
