----------------------------------
Summary: Log if the ipc backoff is enabled in CallQueueManager
Key: HADOOP-15742
URL: https://issues.apache.org/jira/browse/HADOOP-15742
Project: Hadoop Common
Issue Type: Improvement
Affects Versions: 3.1.1
Reporter: Yiqun Lin
Assignee: Ryan Wu
Currently we don't log the info of ipc backoff. It will look good to print this
as well so that makes users know if we enable this.
{code:java}
public CallQueueManager(Class<? extends BlockingQueue<E>> backingClass,
Class<? extends RpcScheduler> schedulerClass,
boolean clientBackOffEnabled, int maxQueueSize, String namespace,
Configuration conf) {
int priorityLevels = parseNumLevels(namespace, conf);
this.scheduler = createScheduler(schedulerClass, priorityLevels,
namespace, conf);
BlockingQueue<E> bq = createCallQueueInstance(backingClass,
priorityLevels, maxQueueSize, namespace, conf);
this.clientBackOffEnabled = clientBackOffEnabled;
this.putRef = new AtomicReference<BlockingQueue<E>>(bq);
this.takeRef = new AtomicReference<BlockingQueue<E>>(bq);
LOG.info("Using callQueue: " + backingClass + " queueCapacity: " +
maxQueueSize + " scheduler: " + schedulerClass);
}
