Running

[rurbanow <ru...@gmail.com>]

Hi,
I have a little haddop, hive, spark, hue setup. I am using hue to try to run
the sample spark notebook. I get the following error messages:

The Spark session could not be created in the cluster: timeout

or

"Session '-1' not found." (error 404)

Spark and livy are up and running.  Searching the web for these error
messages tells me this is a permissions issue relating to the application
history folder and the spark-warehouse directory. On my system, both
directories have 777 permissions.


I also try this:

curl -X POST --data '{"kind": "pyspark"}' -H "Content-Type:
application/json" localhost:8998/sessions

Everything starts, and then I get the following in Hue:

16/10/21 11:17:04 INFO ContextLauncher: 16/10/21 11:17:04 INFO
hive.HiveSharedState: Warehouse path is '/usr/local/spark/spark-warehouse'.

handler.ContextHandler: Stopped
o.s.j.s.ServletContextHandler@37faa18{/static,null,UNAVAILABLE}

This goes on with stopping everything and shutting down other processes.

spark-warehouse folder exists with 777 permissions.
Does anyone have any insight as to why this is happening? Thank you.
