--------------------------------
Summary: LeveldbRMStateStore database can grow substantially
leading to long recovery times
Key: YARN-5008
URL: https://issues.apache.org/jira/browse/YARN-5008
Project: Hadoop YARN
Issue Type: Bug
Components: resourcemanager
Affects Versions: 2.7.0
Reporter: Jason Lowe
Assignee: Jason Lowe
On large clusters with high application churn the background compaction in
leveldb may not be able to keep up with the write rate. This can lead to large
leveldb databases that take many minutes to recover despite not having very
much real data in the database to load. Most the time is spent traversing
tables full of keys that have been deleted.
