[jira] [Created] (YARN-2952) Incorrect version check in
RMStateStore
Jian He created YARN-2952:
-----------------------------
Summary: 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
In RMStateStore#checkVersion: if we modify tCURRENT_VERSION_INFO to 2.0, it'll still store the version as 1.0 which is incorrect;
{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}
