Nathan Roberts commented on YARN-5008: -------------------------------------- Thanks for the patch. LGTM. +1 non-binding > 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 > Attachments: YARN-5008.001.patch > > > 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. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
