Hi all, I've enabled spark notebook on Hue 3.9 in my CDH 5.5.2 cluster. I've started LivyServer in this way: export SPARK_HOME=/opt/cloudera/parcels/CDH/lib/spark export PATH=$PATH:$SPARK_HOME/bin /opt/cloudera/parcels/CDH/lib/hue/build/env/bin/hue livy_server& Then, in a new PySpark notebook I've put this code: a = sc.textFile("/user/admin/index_data.csv") a.count() and I've got this error: 05:43:58.141 [qtp455119019-16] ERROR c.c.hue.livy.server.SessionServlet$ -
