--------------------------------------
Summary: Provide a way to store only running applications in the
state store
Key: YARN-3643
URL: https://issues.apache.org/jira/browse/YARN-3643
Project: Hadoop YARN
Issue Type: Improvement
Components: resourcemanager
Affects Versions: 2.7.0
Reporter: Karthik Kambatla
Today, we have a config that determines the number of applications that can be
stored in the state-store. Since there is no easy way to figure out the maximum
number of running applications at any point in time, users are forced to use a
conservative estimate. Our default ends up being even more conservative.
It would be nice to allow storing all running applications with a conservative
upper bound for it. This should allow for shorter recovery times in most
deployments.
