Splunk Hadoop Connect: Why am I getting error "Invalid header received from stream generating script hdfs"

[lpolo]

I have Splunk Hadoop Connect working fine, however, when I try an hdfs command out of the Hadoop Connect app and run it under one of our apps, I get this error this error in search.log:

06-08-2016 14:13:53.270 ERROR script - sid:1465395233.3253 Invalid header received from stream generating script hdfs

Any idea how to fix this?

Permissions are set to global. hadoop connect is set to run on all apps.

Thanks,
Lp
