Tomás Fernández Löbbe commented on SOLR-7736:
---------------------------------------------
I think we should just return in this particular case. No need to continue
processing in that particular case (the {{updateLock.lockInterruptibly();}}
will generate another InterruptedException that will be logged (again) and
break the while, but no need to wait for that I think.
While looking at this particular class I noticed that other things my throw
InterruptedExceptions that we are just swallowing, like:
{code:java}
scheduledTriggers.add(entry.getValue());{code}
or
{code:java}
List<String> markers =
stateManager.listData(ZkStateReader.SOLR_AUTOSCALING_NODE_LOST_PATH);{code}
this throws {{Exception}} and we catch and log it, but that exception could
actually be an {{InterruptedException}}. Maybe we should change some of those
methods to throw exception types more specific than {{Exception}} (Including
{{InterruptedException}}), that way it will be harder to miss it
