Hi ,   I am upgrading from Spark 1.6.0 to Spark 2.1 on CDH 5.10 platform. I am trying to run spark2-submit command for python implementation and it is failing giving below error. Looks like it is expecting some path property while initilization and creating SparkContext object which is not happening. Error details are as below. Please suggest if any specific configuration is missing or required for spark2.   sc = SparkContext(conf=conf) File "/apps/cloudera/parcels/SPARK2-2.1.0.cloudera1-1.cdh5.7.0.p0.120904/lib/spark2/python/lib/pyspark.zip/pyspark/context.py", line 118, in __init__ File "/apps/cloudera/parcels/SPARK2-2.1.0.cloudera1-1.cdh5.7.0.p0.120904/lib/spark2/python/lib/pyspark.zip/pyspark/context.py", line 182, in _do_init File "/apps/cloudera/parcels/SPARK2-2.1.0.cloudera1-1.cdh5.7.0.p0.120904/lib/spark2/python/lib/pyspark.zip/pyspark/context.py", line 249, in _initialize_context File "/apps/cloudera/parcels/SPARK2-2.1.0.cloudera1-1.cdh5.7.0.p0.120904/lib/spark2/python/lib/py4j-0.10.4-src.zip/py4j/java_gateway.py", line 1401, in __call__ File "/apps/cloudera/parcels/SPARK2-2.1.0.cloudera1-1.cdh5.7.0.p0.120904/lib/spark2/python/lib/py4j-0.10.4-src.zip/py4j/protocol.py", line 319, in get_return_value py4j.protocol.Py4JJavaError: An error occurred while calling None.org.apache.spark.api.java.JavaSparkContext. : java.lang.IllegalArgumentException: Can not create a Path from an empty string at org.apache.hadoop.fs.Path.checkPathArg(Path.java:127) at org.apache.hadoop.fs.Path.<init>(Path.java:135) at org.apache.hadoop.fs.Path.<init>(Path.java:94) at org.apache.spark.deploy.yarn.Client.copyFileToRemote(Client.scala:368) at org.apache.spark.deploy.yarn.Client.org$apache$spark$deploy$yarn$Client$$distribute$1(Client.scala:481) at org.apache.spark.deploy.yarn.Client$$anonfun$prepareLocalResources$13.apply(Client.scala:629) at org.apache.spark.deploy.yarn.Client$$anonfun$prepareLocalResources$13.apply(Client.scala:627) at scala.collection.mutable.ArraySeq.foreach(ArraySeq.scala:74) at org.apache.spark.deploy.yarn.Client.prepareLocalResources(Client.scala:627) at org.apache.spark.deploy.yarn.Client.createContainerLaunchContext(Client.scala:874) at org.apache.spark.deploy.yarn.Client.submitApplication(Client.scala:171) at org.apache.spark.scheduler.cluster.YarnClientSchedulerBackend.start(YarnClientSchedulerBackend.scala:56) at org.apache.spark.scheduler.TaskSchedulerImpl.start(TaskSchedulerImpl.scala:171) at org.apache.spark.SparkContext.<init>(SparkContext.scala:509) at org.apache.spark.api.java.JavaSparkContext.<init>(JavaSparkContext.scala:58) at sun.reflect.NativeConstructorAccessorImpl.newInstance0(Native Method) at sun.reflect.NativeConstructorAccessorImpl.newInstance(NativeConstructorAccessorImpl.java:57) at sun.reflect.DelegatingConstructorAccessorImpl.newInstance(DelegatingConstructorAccessorImpl.java:45) at java.lang.reflect.Constructor.newInstance(Constructor.java:526) at py4j.reflection.MethodInvoker.invoke(MethodInvoker.java:247) at py4j.reflection.ReflectionEngine.invoke(ReflectionEngine.java:357) at py4j.Gateway.invoke(Gateway.java:236) at py4j.commands.ConstructorCommand.invokeConstructor(ConstructorCommand.java:80) at py4j.commands.ConstructorCommand.execute(ConstructorCommand.java:69) at py4j.GatewayConnection.run(GatewayConnection.java:214) at java.lang.Thread.run(Thread.java:745) ...
