I am trying to stream some sstables to Cassandra cluster using SStableLoader utility. I am getting a streaming error. Here is the stack.
Established connection to initial hosts

Also the machine where I am running the sstableloader is out of the cassandra cluster.
Thanks
After debugging a little more, found that sstableloader also uses port 7000 while streaming sstables to cassandra cluster. My local machine did not have access to port 7000 on the machines on cassandra cluster. That's why i was getting connection time out exception.
Anyone who encounters this make sure that your machine from where you are running the sstableloader has access to port 9160,7000 and 9042 of all the casssandra nodes you are trying to stream to.

Hint: I suspect the machine 10.xxx.xxx.xxx is under heavy load. Worth checking the /var/log/cassandra/system.log file on this machine to narrow down the root cause

I am running a spark application on YARN cluster(on AWS EMR). The application seems to be killed and I want to find the cause. I try to understand the YARN info given in the following screen.
The diagnostic line in the screen seems to show that YARN killing the app because of the memory limit:
Diagnostics: Container [pid=1540,containerID=container_1488651686158_0012_02_000001] is running beyond physical memory limits. Current usage: 1.6 GB of 1.4 GB physical memory used; 3.6 GB of 6.9 GB virtual memory used. Killing container.
However, the appattempt log shows completely different exception, something related to the IO/network. My question is : should I trust the diagnostic in the screen or the appattempt log? Is the IO exception causing the kill or the out of memory cause the IO exception in the appattempt log? Is it another log/diagnostic I should look at? Thanks.

The information in your screenshot is the most relevant. Your ApplicationMaster container ran out of memory. You need to increase yarn.app.mapreduce.am.resource.mb which is set in mapred-site.xml. I recommend a value of 2000 since that will usually accommodate running Spark and MapReduce applications at scale.
The container was killed (memory exceeds physical memory limits) so any attempt to reach this container fails.
Yarn is fine to have an overall view of the process, but you should prefer spark history server to analyse better your job (check unbalanced memory in spark history).
I am trying to test Zeppelin 0.6.2 with a Spark 2.0.1 installed in a Windows Server 2012.
I started the Spark master and tested the Spark Shell.
Then I configured the following in the conf\zeppeling-env.cmd file:
set SPARK_HOME=C:\spark-2.0.1-bin-hadoop2.7
set MASTER=spark://100.79.240.26:7077
I have not set the HADOOP_CONF_DIR and SPARK_SUBMIT_OPTIONS (that is optional according to the documentation)
I checked the values in the Interpreter configuration page and the spark master is Ok.
When I run the Zeppelin tutorial --> "Load data into table" note I am getting a connection refused error. Here is part of the messages in the error log:

In the Zeppelin logs there is only one file for zeppelin, the interpreter is an external Spark installation, which is not logging any error because it is never reached by the interpreter process.
I read some suggestion about the max and min memory of the JVM but I could not fix it yet.
Any comment will be appreciated.

I am running a spark streaming application with spark version 1.4.0
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
16/04/01 23:54:20 WARN TaskSetManager: Lost task 141.0 in stage 19859.0 (TID 190333, 192.168.33.96): java.io.IOException: Failed to connect to /192.168.33.97:63276

On relaunching the worker a new executor is allocated but the old (dead) executor's entry is still there and the stages fail with "java.io.IOException: Failed to connect to " error.
I have a hortonwork sandbox 2.4 with spark 1.6 set up. Then I create Intellij spark development environment in windows using hdp spark jar and scala 2.10.5. So both spark and scala version are matched between my windows and hdp environment as indicated here. And my Intellij dev environment works with local as Master.
Then I'm trying to connect hdp in windows using
val sparkConf = new SparkConf()
.setAppName("spark-word-count")
.setMaster("spark://10.33.241.160:7077")
And I get below error information and have no clue to resolve it. Please help!

It turns out I need to setup my hortonworks Spark as master server every time server restart. Then use my intellij dev environment to connect with hdp as slave. Just run ./sbin/start-master.sh in hdp as this link.
I have a test setup in which sstableloader fails to upload data if one of the Cassandra node is down. I can see that
Is there a way to instruct sstableloader not to connect (or open a stream) to the dead node (I don't want to decommission/remove the node from cluster)?
Cassandra cluster info: Datastax community version 2.1.2, 3 node cluster out of which 2 are seed nodes.
During testing bulk upload, one of the seed node was down. The keyspace has replication factor = 2.

Thanks in advance,
Anirban.
I just figured that I can pass an ignore list to sstableloader. By passing dead nodes in the ignore list sstableloader ran successfully in my test setup.
