Research direction

Start in the linkis-computation-governance component and reproduce the three listed steps with Linkis 1.1.2 and the reported CDH, HDP, Hive, Spark, Scala, and JDK environment. Trace the reuse-engine flow after the first task completes, and consider the issue done when a subsequent submission reuses the engine successfully instead of failing.
