Jason Lowe created MAPREDUCE-6141: ------------------------------------- Summary: History server leveldb recovery store Key: MAPREDUCE-6141 URL: https://issues.apache.org/jira/browse/MAPREDUCE-6141 Project: Hadoop Map/Reduce Issue Type: Improvement Components: jobhistoryserver Reporter: Jason Lowe Assignee: Jason Lowe
It would be nice to have a leveldb option to the job history server 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)
