> [while running 'write/Write/WriteImpl/WriteBundles'] {noformat}
> The error happens with Flink 1.5 and Flink 1.8.
> The error does not happen if we run SDK harness in LOOPBACK mode
> (--environment_type=LOOPBACK)
> The error does not happen if we launch Flink jobServer without pointing to a
> Flink cluster, that is if we remove -PflinkMasterUrl=localhost:8081, or if we
> use Spark Jobserver + Spark cluster, so this seems to be a Flink-specific
> problem
> Similar error: https://issues.apache.org/jira/browse/BEAM-7859
> Note that default parallelism parameters set in portableWordCountBatch are
> not compatible with default configuration of standalone Flink cluster, which
> starts with only one available slot.
