@EronWright Thank you for your feedback. When I first developed the
feature, I assumed that HDFS would not be used as default storage because
remote FS failure could affect zeppelin usage. So extended VFSNotebookRepo to
keep the default storage space on local FS and HDFS as backup storage for
failover. This makes the implementation is simple, but it may have created
complexity.
I'm using this feature, but I am also considering using a third-party
storage such as HBase, because the latency of HDFS affects the latency of
zeppelin notebooks.
