https://community.cloudera.com/t5/Support-Questions/Executescript-error/m-p/223482#M185347 <P>Do you have multiple concurrent tasks running? If so, you might be running into <A href="http://bugs.jython.org/issue2642" target="_blank">this issue</A>, and the workaround seems to be to use a single task. If not, are you importing any native (CPython) libraries? You won't be able to do that with Jython, but I thought it gave a different error message in that case.</P> Thu, 25 Oct 2018 20:28:40 GMT mburgess 2018-10-25T20:28:40Z
