Notebook not responding

[Nikhil Utane]

Hi,

I am having a serious issue.
All of a sudden my notebook has stopped responding. The page doesn't load
in any of the browser. I am able to open Tutorial notebooks though.
I have restarted zeppelin daemon but it is not helping.
In the logs, I only see New Connection and Connection Closed messages.
The last changes I made were in a paragraph I added z.show() for two
separate tables. Dunno if that has anything to do or not.

Please help !!

-Regards
Nikhil

Website and doc is part of opensource project and anyone can update them by
making pull request.

https://github.com/apache/zeppelin/blob/master/docs/install/install.md#installation

Please anyone feel free to maintain OS / environment compatibility table.

Thanks,
moon

Excellent.  I am not sure who or how the OS compatibility matrix is
maintained.  But it is good to know that Zeppelin works on CentOS 7.2.
Thanks for sharing.

 Per the Apache Zepplin documentation, CentOS 6 is supported.  CentOS 7
 is NOT mentioned.

 There is actually a very large difference is Linux OS kernels between
 CentOS 6 and CentOS 7.   CentOS 6 is based on the Linux kernel version
 2.6.32-71 while CentOS 7 is based on Linux kernel version 3.10.0-123.  The
 default file system is different as are the run levels.  The init system in
 CentOS 7 is now using systemd and so init is being replaced/updated.  There
 are a lot more changes between CentOS 6 to CentOS 7.

 It sounds like a good opportunity to get involved w/ future development
 of Apache Zeppelin.

I've been running Zeppelin 0.7.1 and no I didn't have to make any
non-standard configuration changes that I recall.  I was very pleased with
how easy it was to get up and running.

Re: Centos 7 Compatibility

[Jim Lola]

Which version of Zeppelin do you have working on CentOS 7.2?  Did you make
any different/non-standard configuration changes to get it to work
properly?  If so, could you please share them.

I have been running Zeppelin on CentOS 7.2 for the last couple of months
without issue.

Centos 7 Compatibility

[Benjamin Kim]

All,

I’m curious to know if Zeppelin will work with CentOS 7. I don’t see it in the 
list of OS’s supported.

Thanks,
Ben

Re: Printing table with variables in pyspark

[Nikhil Utane]

Funny thing happened actually.
I had tried same way as above but removed additional content for simplicity.
I made the mistake of naming my variable as str (Duhh). This then overrode
the standard str() function and because of that whatever I tried failed.

After restarting the interpreter it all worked fine.

Thanks for your help.

Re: Printing table with variables in pyspark

[Jeff Zhang]

This is not zeppelin issue, it is due to your python code, use following
code

str="Col1\tCol2"
print("%table " + str)
