Review comment:
How about the following code?
`
if (tmpMeasurementNode != null) {
IoTDB.metaManager.updateLastCache(node.getFullPath(),
plan.composeLastTimeValuePair(i), true, latestFlushedTime,
tmpMeasurementNode);
} else {
IoTDB.metaManager.updateLastCache(node.getFullPath() +
IoTDBConstant.PATH_SEPARATOR + measurementList[i],
plan.composeLastTimeValuePair(i), true, latestFlushedTime,
tmpMeasurementNode);
}
`
