please note that we currently do not provide any support for the open-source Spark Jobserver. For usage with KNIME Spark Executor we expect everyone to use the Spark Jobserver builds provided on our website. These have been tested by us and contain some additional patches.
To download it and set it up please follow the "Installation Steps" here (there is a installation guide PDF):
Can you pl. let me know, the spark jobserver should be installed on the knime server? or should be installed in the Hadoop cluster?. our knime server is on a different box and our Clouder Hadoop cluster is on different servers.
The jobserver should be installed on an edge node of the Hadoop cluster so that it has full network access to the nodes inside the cluster and at the same time is reachable for clients (KNIME Analytics Platform, KNIME Server) connecting from outside the cluster network. For more details please take a look at the installation guide PDF on the KNIME Spark Executor website:
