TaskSchedulerImpl: Initial job has not accepted any resources

TaskSchedulerImpl: Initial job has not accepted any resources

Guru

Hi,

I'm going to start working with Spark and installed the parcels in our CDH5 GA cluster.

 

Master: hadoop-pg-5.cluster, Worker: hadoop-pg-7.cluster

 

Both daemons are running, Master-Web-UI shows the connected worker, and the log entries show:

master:

Looks good, so far.

 

Now I want to execute the python pi example by executing (on the worker):

cd /opt/cloudera/parcels/CDH/lib/spark && ./bin/pyspark ./python/examples/pi.py spark://hadoop-pg-5.cluster:7077

 

Here the strange thing happens, the script doesn't get executed, it hangs (repeating this output forever) at :

14/04/13 21:31:18 WARN TaskSchedulerImpl: Initial job has not accepted any resources; check your cluster UI to ensure that workers are registered and have sufficient memory

 

The whole log is:

Thereby I have to cancel the execution of the script. If I am doing this, I receive the following log entries on the master (! at cancellation of the python pi script !):

What is going wrong here ?!?!?!?

 

I get the same behaviour if I start the spark-shell on the worker and try to execute e.g. sc.parallelize(1 to 100,10).count

 

any help highly appreciated, Gerd

I would bet that this means that the amount of memory you have requested for your executors exceeds the amount of memory that any single worker of yours has. What are these sizes?

Hi Sean,

 

thanks for your hint, increasing the worker memory settings solved the problem.

I set the worker_max_heapsize to its default val of 512MB (it was just 64MB before) and the total executor memsize to 2GB.

 

thanks, Gerd

Hi I' running cdh5.1.3 libs on cdh5 cluster but when I run spark pgrogramm it gives me  these exception :

When I'm runnig sample examples like wordcount tallSVd it runs fine. what changes I should made to make my appliation should run this script file?
