Jason Lowe created YARN-1185: -------------------------------- Summary: FileSystemRMStateStore doesn't use temporary files when writing data Key: YARN-1185 URL: https://issues.apache.org/jira/browse/YARN-1185 Project: Hadoop YARN Issue Type: Bug Components: resourcemanager Affects Versions: 2.1.0-beta Reporter: Jason Lowe
FileSystemRMStateStore writes directly to the destination file when storing state. However if the RM were to crash in the middle of the write, the recovery method could encounter a partially-written file and either outright crash during recovery or silently load incomplete state. To avoid this, the data should be written to a temporary file and renamed to the destination file afterwards. -- This message is automatically generated by JIRA.
