Ellen Hui commented on YARN-5519:
---------------------------------
The test failed on a timing issue, since the {{MemoryFederationStateStore}}
updates the lastHeartbeat field of a {{SubClusterInfo}} during registration,
causing the stored value and the expected one to differ slightly. I will remove
the line in {{MemoryFederationStateStore}} that modifies the timestamp, so that
the timestamp passed in through the {{SubClusterRegisterRequest}} is stored
unchanged.
