> [lgtm.com|https://lgtm.com] detected two cases where NullPointerExceptions could be triggered when stopping a worker node ([click|https://lgtm.com/projects/g/apache/flink/snapshot/512a3895328d29500458cd03a4c55eea031334eb/files/flink-yarn/src/main/java/org/apache/flink/yarn/YarnResourceManager.java?sort=name&dir=ASC&mode=heatmap&excluded=false#x84390b0ea77b236f:1]) and when adding a task ([click|https://lgtm.com/projects/g/apache/flink/snapshot/512a3895328d29500458cd03a4c55eea031334eb/files/flink-runtime/src/main/java/org/apache/flink/runtime/taskexecutor/slot/TaskSlotTable.java?sort=name&dir=ASC&mode=heatmap&excluded=false#xb891777ba106b132:1]).
