But in real use cases, base major version can be greater than 2 or 3 which installation itself will fail. > Incorrect version check in RMStateStore > --------------------------------------- > > Key: YARN-2952 > URL: https://issues.apache.org/jira/browse/YARN-2952 > Project: Hadoop YARN > Issue Type: Bug > Reporter: Jian He > Assignee: Rohith > > In RMStateStore#checkVersion: if we modify tCURRENT_VERSION_INFO to 2.0, > it'll still store the version as 1.0 which is incorrect; The same thing might > happen to NM store, timeline store. > {code} > // if there is no version info, treat it as 1.0; > if (loadedVersion == null) { > loadedVersion = Version.newInstance(1, 0); > } > if (loadedVersion.isCompatibleTo(getCurrentVersion())) { > LOG.info("Storing RM state version info " + getCurrentVersion()); > storeVersion(); > {code} -- This message was sent by Atlassian JIRA (v6.3.4#6332)
