-----------------------------------
Summary: Auxillary Service status on NodeManager UI / Cli
Key: YARN-7429
URL: https://issues.apache.org/jira/browse/YARN-7429
Project: Hadoop YARN
Issue Type: Bug
Components: nodemanager
Affects Versions: 2.7.3
Reporter: Prabhu Joseph
Priority: Major
When Auxillary services like Spark Shuffle , MapReduce Shuffle Service fails
for some reason, and the jobs running will have issue when the remote
containers tries to fetch the data from the Node where service is failed to
initialize.
Reason shuffle service failed to start will be in NodeManager logs during
startup and likely will be lost after few days when we noticed the jobs
failing. Useful if NodeManager UI / Cli shows the list of Auxillary Services
and their status and capture any error message if it has failed.
