[SPARK-12275][SQL] No plan for BroadcastHint in some condition - 1.5 …
…backport backport #10265 to branch 1.5 When SparkStrategies.BasicOperators's "case BroadcastHint(child) => apply(child)" is hit, it only recursively invokes BasicOperators.apply with this "child". It makes many strategies have no change to process this plan, which probably leads to "No plan" issue, so we use planLater to go through all strategies. https://issues.apache.org/jira/browse/SPARK-12275
