Till Rohrmann created FLINK-1533: ------------------------------------ Summary: NullPointerException in SlotSharingGroupAssignment.addSharedSlotAndAllocateSubSlot Key: FLINK-1533 URL: https://issues.apache.org/jira/browse/FLINK-1533 Project: Flink Issue Type: Bug Reporter: Till Rohrmann
The scheduler can fail with a NullPointerException if it is not possible to allocate a {{SharedSlot}} from an {{Instance}}. In the method {{Scheduler.getFreeSubSlotForTask}} the allocated {{SharedSlot}} is not checked that it is not null. This can cause a program to fail if there is a race condition in scheduling different tasks on the same instance. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
