We're currently attempting to submit Spark jobs via Talend, and we're hitting the following error:
[ERROR]: org.apache.spark.SparkContext - Error initializing SparkContext.java.lang.RuntimeException: java.lang.RuntimeException: java.lang.ClassNotFoundException: Class org.apache.hadoop.yarn.client.RequestHedgingRMFailoverProxyProvider not found at org.apache.hadoop.conf.Configuration.getClass(Configuration.java:2227)
I've ensured the YARN classpath is updated (as noted in this post on the HWX forums), but we're still getting the above error. Not sure if we're not setting something in Ambari or if something is not being set in Talend. All help is appreciated.
There is not enough information for us to address your issue.
Could you please indicate on which talend big data build version you got this issue? What's the setting of your Spark jobs? Screenshots will be preferred.
