Can I run the hadoop jar by knime?

I write some mapreduce jobs of hadoop that I want to use knime to show as a flow chart. But there is a question that I don’t know how to run those jobs in hadoop cluster by knime.
Can anyone help me ?
Thanks a lot.

Hi @mugun
We do have Spark nodes, that enable you to use Spark on a Hadoop Cluster directly from KNIME. However there are no MapReduce nodes.
You could use a Java Snippet node to trigger the jobs. And use the HDFS connection to access the output of the jobs.
