Ying Zheng updated FALCON-2073:
-------------------------------
Description:
Coverity scan finds a few places where the return value of an object could be
NULL but Falcon tries to access its member without handling with the corner
NULL case. For example, cluster update could run into an error if there is no
dependent entity for the cluster, see OozieWorkflowEngine::updateDependents:
{code}
Set<Entity> affectedEntities =
EntityGraph.get().getDependents(oldEntity);
for (Entity affectedEntity : affectedEntities) {
......
}
{code}

Coverity scan finds a few places where the return value of an object could be
NULL but Falcon tries to access its member without handling with the corner
NULL case. For example, in OozieWorkflowEngine::updateDependents, we will run
into an error if there is no dependency edge for the oldEntity:
{code}
Set<Entity> affectedEntities =
EntityGraph.get().getDependents(oldEntity);
for (Entity affectedEntity : affectedEntities) {
......
}
{code}
