Aljoscha Krettek commented on FLINK-10368:
------------------------------------------
[~till.rohrmann] said we should at checks to the code that see if the cluster
could be brought up and then exit the test gracefully without failing when it
can't be brought up.
> 'Kerberized YARN on Docker test' instable
> -----------------------------------------
>
> Key: FLINK-10368
> URL: https://issues.apache.org/jira/browse/FLINK-10368
> Project: Flink
> Issue Type: Bug
> Components: Tests
> Affects Versions: 1.5.3, 1.6.0, 1.7.0
> Reporter: Till Rohrmann
> Priority: Critical
> Labels: test-stability
> Fix For: 1.7.0
>
>
> Running Kerberized YARN on Docker test end-to-end test failed on an AWS
> instance. The problem seems to be that the NameNode went into safe-mode due
> to limited resources.
