> Currently we try reading chunk data from the temp file if chunk file does not exist. The fix was added in HDDS-2372 due to race condition between readStateMachineData and writeStateMachineData in ContainerStateMachine. After HDDS-2542 is fixed the read from the temp file can be avoided by making sure that chunk data remains in cache until the chunk file is generated.
