Jian He commented on YARN-2765: ------------------------------- thanks Jason for working on this. It's useful to have leveldb as an option for RMStateStore, as its more lightweight compared to others. reviewing the patch > Add leveldb-based implementation for RMStateStore > ------------------------------------------------- > > Key: YARN-2765 > URL: https://issues.apache.org/jira/browse/YARN-2765 > Project: Hadoop YARN > Issue Type: Sub-task > Components: resourcemanager > Reporter: Jason Lowe > Assignee: Jason Lowe > Attachments: YARN-2765.patch, YARN-2765v2.patch > > > It would be nice to have a leveldb option to the resourcemanager recovery > store. Leveldb would provide some benefits over the existing filesystem store > such as better support for atomic operations, fewer I/O ops per state update, > and far fewer total files on the filesystem. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
