When I try to execute a node in KNIME, for instance a bash node, where the command is controlled by a flow variable, KNIME gives me a warning.
" WARN Bash Errors overwriting node settings with flow variables: Unknown variable "Variablename" "
I then see the job when I 'qstat', but it doesn't seem to execute and gives me an eclipse error and in the knime console gives me the following error.
"ERROR AbstractClusterJob Execution of node did not succeed on cluster: reason unknown."
However when I actually type in the command (ie not control the command field with a flow variable) it works fine and returns the output.
