-----------------------------------
Summary: Doing updatePriority is blocking when using FairScheduler
Key: YARN-9329
URL: https://issues.apache.org/jira/browse/YARN-9329
Project: Hadoop YARN
Issue Type: Bug
Reporter: Jiandan Yang
Assignee: Jiandan Yang
updating priority is blocked when using FairScheduler, the command is as
follows:
{code:java}
bin/yarn application -appId application_1550834280474_0003 -updatePriority 500
{code}
The RM rpc handler thread is blocked in the future.get(), although
FairScheduler does not support priority currently, it is not friendly to user
when executing updatePriority.
The trace of handler is:
{code:java}
