I just changed them to be more clear in grpc/grpc-java#4106. Each message 
gets its own gRPC frame, but the very fact there are gRPC frames is more of an 
internal detail; users shouldn't need to know about such things.

 Summary: iPython shell (! magic command) doesn't print
 Key: ZEPPELIN-3260
 URL: https://issues.apache.org/jira/browse/ZEPPELIN-3260
 Project: Zeppelin
  Issue Type: Bug
  Components: Core, front-end, pySpark, python-interpreter
Affects Versions: 0.8.0, 0.9.0
Reporter: Ruslan Dautkhanov
 Attachments: image-2018-02-23-10-38-07-304.png

 
{code:java}
%ipyspark
! !echo 1; sleep 1; echo 2
{code}
uses ipython's shell magic command (! - exclamation mark), but in Zeppelin it 
prints just two empty lines:

!image-2018-02-23-10-38-07-304.png!

Should have printed two lines with "1" and "2" in them.

[jira] [Created] (ZEPPELIN-3259) Improve code-completion in Zeppelin to support true intellisense

 Summary: Improve code-completion in Zeppelin to support true 
intellisense
 Key: ZEPPELIN-3259
 URL: https://issues.apache.org/jira/browse/ZEPPELIN-3259
 Project: Zeppelin
  Issue Type: Improvement
Affects Versions: 0.7.3
Reporter: Gesly George


Can we get true intelli-sense in Zeppelin like in Jupyter?

For starters, if we could get method completion and method parameters on Ctrl + 
., that would be a start.

Right now Ctrl + . just list various variables and keywords. Can we show the 
methods on a variable when press Ctrl + . and what parameters those methods 
take? I think that would be very useful.
