If I run a single job with spark on yarn-client everything works fine, but on multiple (>1) concurrently jobs I get the following exception on the container nodes. I'm Using Spark 1.2 with CDH5.3 and Spark-Jobserver

Check SparkConf.set("spark.cleaner.ttl", "10000") in SparkConf. It may be due value in spark.cleaner.ttl your program running time exceeds the corresponding value, this may happens. Just increase the value. its given in seconds.
For more details look at configuration.html
it shouldn't be the reason spark.cleaner.ttl, since it was deprecated since Spark1.4

I have an error happening in spark running on Amazon EMR.
It doesn't always happen (most of the time the step finishes successfully) and when I work with more data and more nodes it happens more often.
I get a file already exists exception, but the question is what does it mean "failed 20 times"? What exactly failed? And why after 20 times it makes the whole application fail? Where is the configuration for that?
This is from the stderr of the step: (I blanked private info with *)

The strange thing is, I can't even see the lost executors on the Executor list for the log.
It would be great if someone can help fix the problem.
There are many factors for this to happen but the summary is the following:
Your master node is unable to reply to a specific executor and therefore gives the error
Unable to register with external shuffle server due to
Why your master node is unable to reply can be of different reasons. Depends on how your code is structured, the size of your instance if you are using EMR.
To solve it
Increase your master node. For example, if you are using i3.4xlarge, instead use i3.8xlarge or even i3.16xlarge.
Increase the network timeout from 2 minutes to 5 minutes. This is done with the following spark configuration: spark.network.timeout=300
Increase both the memory and number of cores of your master node. To increase the number of cores of your master node, set the following configuration. spark.yarn.am.cores=3
Hope this solves the issue.
I am running a spark application on yarn, which my goal is do some ETL from jdbc to elasticsearch.
However, when I check the log ,there is some errors like,this error is due to network problem :

This means that connection failed and lost some data in this process.The job finalStatus should be failed, but spark returned me with {"state":"FINISHED","finalStatus":"SUCCEEDED"}
WHY? My spark version is 2.2.0
I have a PySpark job which works successfully with a small cluster, but starts to get a lot of the following errors in the first few minutes when it starts up. Any idea on how I can solve it? This is with PySpark 2.2.0 and mesos.

If I kill the worker (using kill -9) when my job is running, then the worker and executor both on that node dies,but it still shows up in the executors tab of the UI. The number of active tasks sometimes shows as negative on those executors.
Because of this the jobs keep on failing with the following exception
