Lars Volker has uploaded a new patch set (#3). Change subject: IMPALA-4329: Prevent crash in scheduler when no backends are registered ......................................................................
IMPALA-4329: Prevent crash in scheduler when no backends are registered The scheduler crashed with a segmentation fault when there were no backends registered: After not being able to find a local backend (none are configured at all), the previous code would eventually try to return the top of assignment_ctx.assignment_heap SelectRemoteBackendHost(), but that heap would be empty. Subsequently, when using the IP address of that heap node, a segmentation fault would occur. This change adds a check and aborts scheduling with an error. It also contains a test.
