Hi all, I resolved the mistery 🙂 it was a fw (content filter, not packet) issue. While I can connect with telnet to the specified port, some http packets were blocked. We noticed that our office fw logs this message: 2016-02-04 15:47:58 Deny 192.168.0.128 40.112.76.49 http/tcp 57772 9995 1-Ecube 0-Internet ProxyDeny: HTTP Invalid Request-Line Format (TCP-UDP-isoardi OUT-00) HTTP-Client.isoardi proc_id="http-proxy" rc="594" msg_id="1AFF-0005" proxy_act="HTTP-Client.isoardi" line="\x81\x8d\xf2\x9eW\xfe\x89\xbc8\x8e\xd0\xa4u\xae\xbb\xd0\x10\xdc\x8f\x81\x8d\xf8]\xb8z\x83\x7f\xd7\x0a" Traffic I don't know if it is an issue related to the fw (watchguard xtm) or to a strange response from Zeppelin web page that the fw discards, but disabling the content filter for the domain on which our zeppelin instance runs all goes fine. Thank all for the time you spent, D.

@Artem Ervits I don't think this is the same case, nss is installed on my edge node [root@hdpedge01 ~]# yum list installed nss Loaded plugins: fastestmirror Loading mirror speeds from cached hostfile * epel: mirror.bytemark.co.uk Installed Packages nss.x86_64 3.19.1-19.el7_2 @updates [root@hdpedge01 ~]# Thank you, D.

@Artem Ervits same issue, either after a "restart" and a "stop-and-start" [zeppelin@hdpedge01 zeppelin-0.6.0-incubating-SNAPSHOT]$ ./bin/zeppelin-daemon.sh restart Zeppelin stop [ OK ] Zeppelin start [ OK ] [zeppelin@hdpedge01 zeppelin-0.6.0-incubating-SNAPSHOT]$ ./bin/zeppelin-daemon.sh stop Zeppelin stop [ OK ] [zeppelin@hdpedge01 zeppelin-0.6.0-incubating-SNAPSHOT]$ ./bin/zeppelin-daemon.sh start Zeppelin start [ OK ] [zeppelin@hdpedge01 zeppelin-0.6.0-incubating-SNAPSHOT]$

Hi @Artem Ervits, thank you for the response. I tried the tutorial you posted, but get the same issue. Following, there are the print screen, in which you can see that in the interpreter page all is fine, but I get a "Disconnected" status on the Notebook tab Thank you, D.

Hi all, i'm trying to install & start apache zeppelin on an Ambari managed cluster (IAAS on Azure), without success. I'm using the ambari service from github, the installation goes fine, and I can start Zeppelin successfully. But when I try to connect, I see no welcome page neither notes, and if I try to add a note nothing happens. Either ports 9995 and 9996 are open and reachable. This is my configuration: Edge node (just zeppelin and clients): Centos (OpenLogic) 7.2 HDP 2.3.4 Ambari 2.2.0 Apache Zeppelin 0.5 (pre-built) No errors in zeppelin's logs, except for this 4 warnings in the *.out log: WARNING: The following warnings have been detected with resource and/or provider classes: WARNING: A HTTP GET method, public javax.ws.rs.core.Response org.apache.zeppelin.rest.InterpreterRestApi.listInterpreter(java.lang.String), should not consume any entity. WARNING: A sub-resource method, public javax.ws.rs.core.Response org.apache.zeppelin.rest.NotebookRestApi.createNote(java.lang.String) throws java.io.IOException, with URI template, "/", is treated as a resource method WARNING: A sub-resource method, public javax.ws.rs.core.Response org.apache.zeppelin.rest.NotebookRestApi.getNotebookList() throws java.io.IOException, with URI template, "/", is treated as a resource method I attach the zeppelin-env.sh and the zeppelin-site.xml files. Thank you in advance! zeppelin-conf.tar.gz

Hi, Thank you for the info! No, i'm not looking for a particular feature, i just need to index some flowfiles with elastic, as I do with solr now. Thank again!

Hi all, Is there anything in the roadmap to add a processor like PutSolrContentStream, but to send data to ElasticSearch? Thank you, D.

vergari · ‎01-12-2016

Ok, thank you very much, Joe. I'll try this way.

vergari · ‎01-11-2016

Hi Joe, thanks for the response. I'm sorry, I badly explained myself. I'm not looking for a geo enrichment based on an IP address, but on a street address. For example, in my FlowFile, I have an attribute named "address" which contains a street address eg. "1234 Main Street, SomeCity, USA" and I need to query an external GIS database to get lat and long for that address. Thanks Davide
