I try to start a new session to run any engine kernel, Python or Scala or R. There is a an error "target is not defined". i have run "cdsw validate" and there is no error. What target has not been defined and cause the error?

Hi Pollylaw,

Have you set JAVA_HOME in your the Administration settings? There is a known issue in 1.0.1 with custom JAVA_HOME directories that can lead to this error message. A workaround is to remove JAVA_HOME from Admin > Engines and make sure Java is located at a location that can be detected by the bigtop-detect-javahome.sh script. This will be fixed in a future release.

Please let us know if this workaround does not solve your issue or if this explanation does not match your configuration.
