A follow up.
I am running zeppelin as a service on a Fedora 25 server controlled by
systemd (systemctl ...). I create a user and group, zeppelin, with
/sbin/nologin and home /dir1/zeppelin. I set up shiro.ini for my ldap
authetication. This issue did not occur when I was testing, starting
server with command line script or daemon as root user, and logging in
as anonymous on the zeppelin url.
Googleviz charts do work, only R specific plot, ggplot2, have this issue.
Thanks
Joe
