--------------------------------
Hi, [~leftnoteasy].
Can we improve the skip queue log in ParentQueue#assignContainers? In
async-scheduling mode, there are too many such debug logs (thousands every
second) and may generate several new log files every minute when there is no
pending request on the root queue. I think this log can be printed at periodic
intervals.
{code:java}
if (!super.hasPendingResourceRequest(candidates.getPartition(),
clusterResource, schedulingMode)) {
if (LOG.isDebugEnabled()) {
LOG.debug("Skip this queue=" + getQueuePath()
+ ", because it doesn't need more resource, schedulingMode="
+ schedulingMode.name() + " node-partition=" + candidates
.getPartition());
}
...
}
{code}
