Hi,
-not sure if my 1st email has reached the mailing list, I just subscribed to
the list a few minutes ago-
I'm trying to use Zeppelin 0.10.1 in Docker and store notebooks on HDFS from
our Hadoop cluster.
Nevertheless, as soon as I set :
<property>
<name>zeppelin.notebook.storage</name>
<value>org.apache.zeppelin.notebook.repo.FileSystemNotebookRepo</value>
<description>notebook persistence layer implementation</description>
</property>
in zeppelin-site.xml, the workload is not able to start. The stacktrace is as
follow :

I have built the project from sources, but same error. I have also tried to
explicitly add Hadoop-common dependency in the pom of NotebookRepo, but same
error again at runtime.
What am I making wrong ?
