I installed Hadoop 2.8 , Spark 2.1.1 Single node in VM

and Rapidminer 7.5.001 , Radoop 7.5

 

I selected "Apache Hadoop 2.2+" in Radoop Connection.

 

I validated Spark installation with SparkPi.

Quick Test finished successfully.

 

I got following error in yarn for Full Test(only Spark Job selected) :

The error say "Input path does not exist: file:/tmp/radoop/root/tmp_1498687861970_0idqr77"

but I found that folder in HDFS , also it has a file with sample data .

 

Permission for that folder is "drwxrwxrwx".

 

Connection and logs are attached.

 

Any solutions ?

    I see.

     

    But I also wrote "If this does not work, the multi-line default value that is described in the link above for this property can be copy-pasted to the value cell instead." :) What happens, if you set the value from here?

    https://hadoop.apache.org/docs/r2.8.0/hadoop-yarn/hadoop-yarn-common/yarn-default.xml

     

    $HADOOP_CONF_DIR, $HADOOP_COMMON_HOME/share/hadoop/common/*, $HADOOP_COMMON_HOME/share/hadoop/common/lib/*, $HADOOP_HDFS_HOME/share/hadoop/hdfs/*, $HADOOP_HDFS_HOME/share/hadoop/hdfs/lib/*, $HADOOP_YARN_HOME/share/hadoop/yarn/*, $HADOOP_YARN_HOME/share/hadoop/yarn/lib/*

     

    I wonder if these env variables work on the cluster or not....

    Hi,

     

    the path in the error: "file:/tmp/radoop/root/..." indicates that there is a configuration problem in the submitted Spark job. Meaning that it looks for the file on the local filesystem (on the particular node) instead of the HDFS. (The configuration makes HDFS accessible. The "Wrong FS: hdfs..." message in the stderr.html also indicates that.)

     

    In the connection xml, the "yarn.application.classpath" setting is strange. It makes the classpath of the submitted job empty, so then the configuration on the cluster is not loaded in the job - this may be the cause behind the error. Disabling or removing it may make a difference.

     

    Best,

    Peter

    I added "yarn.application.classpath" with empty value according to your suggestion in the following topic becasue I had same problem.

    Radoop connection error (Failed: fetching dynamic settings)

     

    If I remove that old problem will be back.
