When the service first starts, the Ambari Dashboard shows a green status indicator. After a minute or so, it goes red, despite the fact that the service is still live.

Installed on Ambari 2.0.1, HDP 2.2. HDFS/YARN/Tez/Zookeeper/Spark/Metrics

words = sc.textFile("file:///tmp/hello.txt")

NameError: name 'sc' is not defined

I'm getting this error when trying to install the service:

Traceback (most recent call last):

It would be great to add NLTK to the default set of packages installed.

I have a cluster with HDP 2.4.2 and Ambari 2.2.2 with Kerberos authentication on CentOS 7.

After solved the issue in file ambari_helper.py (see issue #6) I try to reinstall Jupyter but I get this message error

resource_management.core.exceptions.Fail: Execution of 'hadoop fs -mkdir -p /user/jupyter' returned 1. 16/07/26 16:08:30 WARN ipc.Client: Exception encountered while connecting to the server : 
javax.security.sasl.SaslException: GSS initiate failed [Caused by GSSException: No valid credentials provided (Mechanism level: Failed to find any Kerberos tgt)]

("Create Principals" and "Create Keytabs" have finished "OK".)

Thanks in advance.

seems there is a python 2.7.9 conflict with the installer in Centos/RHEL 6.6

Will this service work with a kerberos secure cluster?
Is this jupyter ipython notebook multiuser now? Or do I have to use https://github.com/jupyter/jupyterhub instead of this service?

Thanks

Hi,

I installed this service on a cluster of 5 host (Jupyther server on host-4 and client on the other ones). Each hosts have 8 cores.

When I see on the tab "Cluster" of Jupiter Web UI" it tells that only 8 cores are available: I expect that should be all host-clients in this tab!

Any suggestions?

Whenever i run localhost:9999 on my host server, Jupyter stops in Ambari, any work around for this?
