Hi Zeppelin users, I'm trying out Zeppelin before I can deploy it on Amazon EMR, but I seem to be running into the error mentioned in the subject. In the page it says: "Problem accessing /. Reason: Service. Unavailable". I'm using the pre-compiled download with Spark 2.1.1 and Hadoop 2.7.3 (on a single node, my laptop). I can start a spark (or pyspark) shell, use HDFS, and run small spark jobs.
Some searching tells me, similar http errors are common, but none of the resolutions seem to work for me. What I have tried include checking if the webapps directory is writable: $ ll -d webapps/ drwxrwxr-x. 1 jallad jallad 12 Jul 22 20:42 webapps/ /tmp is writable: $ ll -d /tmp/Jetty_* drwxrwxr-x. 3 jallad jallad 60 Jul 22 20:41 /tmp/Jetty_0_0_0_0_50070_hdfs____w2cu08 drwxrwxr-x. 3 jallad jallad 60 Jul 22 20:41 /tmp/Jetty_0_0_0_0_50090_secondary____y6aanv drwxrwxr-x. 4 jallad jallad 80 Jul 22 20:42 /tmp/Jetty_0_0_0_0_8042_node____19tj0x drwxrwxr-x. 4 jallad jallad 80 Jul 22 20:42 /tmp/Jetty_0_0_0_0_8088_cluster____u0rgz3 drwxrwxr-x. 3 jallad jallad 60 Jul 22 20:41 /tmp/Jetty_localhost_39637_datanode____5b8f6j You can find the logs here: - zeppelin-jallad-host.log: https://pastebin.com/mByZ80DR - zeppelin-jallad-host.out: https://pastebin.com/6dwkgnsn So what am I missing? Can someone help? Btw, I also quickly tried out Zeppelin on EMR, and I seem to be getting an empty zeppelin home page, with no links to create a notebook. That's what prompted me to try it out on my laptop. Thanks, -- Suvayu Open source is the future. It sets us free.
