@zjffdu As this fixes a regression from 
[ZEPPELIN-3013](https://issues.apache.org/jira/browse/ZEPPELIN-3013) would you 
mind helping here out?

@kjmrknsn, if user knows zeppelin url, why he doesn't know about the need 
of LDAP account?

I believe that the custom welcome header is not nice way for announcing.
One may support guest account with open password.
Also the homescreen is excellent new feature, if it will be.

[jira] [Created] (ZEPPELIN-3126) More than 2 notebooks in R failing with error sparkr intrepreter not responding

 Summary: More than 2 notebooks in R failing with error sparkr 
intrepreter not responding
 Key: ZEPPELIN-3126
 URL: https://issues.apache.org/jira/browse/ZEPPELIN-3126
 Project: Zeppelin
  Issue Type: Bug
  Components: r-interpreter
Affects Versions: 0.7.2
 Environment: spark version 1.6.2


Reporter: Meethu Mathew
Priority: Critical


Spark interpreter is in per note Scoped mode.
Please find the steps below to reproduce the issue:
1. Create a notebook (Note1) and run any r code in a paragraph. I ran the 
following code.
%r
rdf <- data.frame(c(1,2,3,4))
colnames(rdf) <- c("myCol")
sdf <- createDataFrame(sqlContext, rdf)  
withColumn(sdf, "newCol", sdf$myCol * 2.0)

2.  Create another notebook (Note2) and run any r code in a paragraph. I ran 
the same code as above.

Till now everything works fine.

3. Create third notebook (Note3) and run any r code in a paragraph. I ran the 
same code. This notebook fails with the error 
org.apache.zeppelin.interpreter.InterpreterException: sparkr is not responding 

The problem will be solved on restarting the sparkr interpreter and another 2 
models could be executed successfully. But again, for the third model run using 
the sparkr interpreter, the error is thrown. 
Once a notebook throws the error, all further notebooks will throw the same 
error and each time we run those failed notebooks, a new R shell process will 
be started and these processes are not getting killed even if we we delete the 
failed notebook.i.e it does not reuse original R shell after failure
