---------------------------------------
Summary: AutoParallellismITCase fails with Flip6
Key: FLINK-8813
URL: https://issues.apache.org/jira/browse/FLINK-8813
Project: Flink
Issue Type: Bug
Components: JobManager, Tests
Affects Versions: 1.5.0
Reporter: Chesnay Schepler
Fix For: 1.5.0
The {{AutoParallelismITCase}} fails when running against flip6.
([https://travis-ci.org/zentol/flink/jobs/347373854)]
It appears that the {{JobMaster}} does not properly handle
{{ExecutionConfig#PARALLELISM_AUTO_MAX}}.
Exception:
{code:java}
Caused by: org.apache.flink.runtime.client.JobSubmissionException: Could not
start JobManager.

The likely culprit is this call to {{ExecutionGraphBuilder#buildGraph}} in the
{{JobMaster}} constructor:
{code:java}
this.executionGraph = ExecutionGraphBuilder.buildGraph(
null,
jobGraph,
jobMasterConfiguration.getConfiguration(),
scheduledExecutorService,
scheduledExecutorService,
slotPool.getSlotProvider(),
userCodeLoader,
highAvailabilityServices.getCheckpointRecoveryFactory(),
rpcTimeout,
restartStrategy,
jobMetricGroup,
-1, // parallelismForAutoMax
blobServer,
jobMasterConfiguration.getSlotRequestTimeout(),
log);{code}
