----------------------------------
Summary: Reduce the number of NameNode access when starting the
Yarn job
Key: OOZIE-3678
URL: https://issues.apache.org/jira/browse/OOZIE-3678
Project: Oozie
Issue Type: Improvement
Affects Versions: 5.2.1
Reporter: Janos Makai
Assignee: Janos Makai
Before Oozie starts the Yarn application it assembles the class path which's
elements' paths are resolved with
{code:java}
remoteFS.resolvePath(p){code}
which can cause slowness and high NameNode load.
The intention is to make this path resolution configurable (ability to turn it
on/off) via an Oozie configuration thus customers can turn it off when they
experience job start slowness. Default value should result the new behaviour is
active.
