[jira] [Created] (ZEPPELIN-2116) %livy interpreter needs to restart after previous session timeout

[Kshitij Badani (JIRA)]

Kshitij Badani created ZEPPELIN-2116:


 Summary: %livy interpreter needs to restart after previous session 
timeout
 Key: ZEPPELIN-2116
 URL: https://issues.apache.org/jira/browse/ZEPPELIN-2116
 Project: Zeppelin
  Issue Type: Bug
  Components: livy-interpreter
Affects Versions: 0.7.0
Reporter: Kshitij Badani
 Fix For: 0.7.0


1) Reduce livy.session.timeout = 30 (5 min)
2) I started a long running job
%livy
print(1)
Thread.sleep(40)
print(2)

This scenario runs fine.
3) After a period of inactivity, the livy session times out. I can see that on 
RM UI - the livy session state is FINISHED
4) Now in the same notebook, if I try to do
%livy
sc.version
It gives 404 Error

works

[jira] [Created] (ZEPPELIN-2115) Could not rename .note.json to note.json in afterStatusChange after a terminated job

 Summary: Could not rename .note.json to note.json in 
afterStatusChange after a terminated job
 Key: ZEPPELIN-2115
 URL: https://issues.apache.org/jira/browse/ZEPPELIN-2115
 Project: Zeppelin
  Issue Type: Bug
Affects Versions: 0.7.0
Reporter: Frank Rosner


h4. Problem

When using a notebook on some actions we are getting the following error 
messages. Looking at the filesystem after some time we actually are able to see 
the file so it managed to rename it eventually. Could that be some kind of race 
condition when editing the note while some jobs are running or running 
different jobs (of different interpreters) at the same time?

It happened, e.g., when clicking "run all" but also in other situations it 
seems.

[GitHub] zeppelin pull request #2018: [ZEPPELIN-2114]: Adding an endpoint in Notebook...

[Remilito]

GitHub user Remilito opened a pull request:

https://github.com/apache/zeppelin/pull/2018

[ZEPPELIN-2114]: Adding an endpoint in NotebookRepoRestApi to reload note 
list

### What is this PR for?
Adding endpoint in NotebookRepoRestApi to trigger reload and broadcast of 
the note list.
Sending a GET request to /api/notebook-repositories/reload will trigger a 
reload of the note list, just like the reload button does on the homepage.
Q: If you think this endpoint belongs to another API (NotebookRestApi?), 
let me know.

### What type of PR is it?
Improvement

### Todos
* [ ] - Task

### What is the Jira issue?


### How should this be tested?
0. add (or remove) a note in the notebook repository
1. curl -x GET http://HOST:PORT/api/notebook-repository/reload
2. verify that you the note list in Zeppelin's home page now contains (or 
does not contain anymore) the note.

### Screenshots (if appropriate)

### Questions:
* Does the licenses files need update? NO
* Is there breaking changes for older versions? NO
* Does this needs documentation? NotebookRepoRestApi does not have 
documentation yet. Could add it in another PR if needed.

### What is this PR for?

yarn installed by frontend-maven-plugin causes build failure **when there 
is no nodeJS in local system**

To reproduce this bug

- Remove system nodejs

 Details.

- yarn installed by frontend-maven-plugin can't run commands described in 
scripts tag (`package.json`)
- but npm is able to execute them. 
- so, it's bug of the maven plugin.
