Prabhu Joseph created TWILL-157:
-----------------------------------
Summary: ApplicationMasterService does not reconnect to RM when it
restarts
Key: TWILL-157
URL: https://issues.apache.org/jira/browse/TWILL-157
Project: Apache Twill
Issue Type: Bug
Affects Versions: 0.6.0-incubating
Reporter: Prabhu Joseph
When we run a YARN job with the ApplicationMaster developed using Twill, the
job is failing during the restart of RM with Connectionrefused. We expect it to
reconnect like MRAppMaster.
