'Kerberized YARN on Docker test' unstable

    XMLWordPrintableJSON

Details

    Description

      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.

Running the Flink job failed, might be that the cluster is not ready yet. We have been trying for 795 seconds, retrying ...

      I think it would be good to harden the test.
