Remote connect shows Disconnected
Hi Team:
Zeppelin is OK in localhost. But when I open it in another machine, it shows disconnected every few seconds.
we use nginx as a websocket reverse proxytoconnection between a client and server. Zeppelin in server and I open a c
Inzeppelin-site.xml,I set:
export MASTER=spark://BJ-BIGDATA-01:7077
export HADOOP_CONF_DIR=/usr/hadoop/etc/hadoop/
export ZEPPELIN_PORT=10008
Inzeppelin-site.xml, I have only set server ip address and port and -1 for websocket port.
I tail the log/zeppelin-hadoop*.logwhen it shows disconnected(on the right corner),it print line like“...Closed connection to 10.12.12.51 : 49622”, and when i press F5 to fresh the page shows connected,the logs print line like“...New connection from 10.12.12.51 : 49946”,and when i finished the job, it print“..closed connection to 10.12.12.51 : 51863” too.

Hi,
Can you try to run some paragraphs when the status is disconnected?
It could be a bug from the disconnected status on the UI.
Also which version are you using? (since there was a commit about fixing
that before)
