------------------------------------------
Summary: Distributed shell app in Yarn service check may be slow
Key: AMBARI-12217
URL: https://issues.apache.org/jira/browse/AMBARI-12217
Project: Ambari
Issue Type: Bug
Components: ambari-server
Affects Versions: 2.1.0
Reporter: Vitaly Brodetskyi
Assignee: Vitaly Brodetskyi
Priority: Critical
Fix For: 2.1.0
Yarn service check today runs a distributed shell application with
num_containers = num_nodes_in_cluster. This could be a problem on production
cluster because the num_nodes could be very large, therefore the service check
may run slow.
We may just change it back to launch 1 container.
