Jose Luis Lopez Pino commented on FLINK-989:
--------------------------------------------
I think this also applies to some other exceptions in the job manager, they are
not very descriptive. I can send a pull request that fixes some of them, if you
want to.
A couple of examples:
{code:title=DefaultScheduler.java|borderStyle=solid}
} catch (InstanceException e) {
final String exceptionMessage =
StringUtils.stringifyException(e);
LOG.error(exceptionMessage);
this.jobQueue.remove(executionGraph);
throw new SchedulingException(exceptionMessage);
}
{code}
{code:title=DefaultScheduler.java|borderStyle=solid}
switch (outputGate.getChannelType()) {
case NETWORK:
deployTarget = false;
break;
case IN_MEMORY:
deployTarget = true;
break;
default:
throw new IllegalStateException("Unknown
channel type");
}
{code}
