Workaround is adding "org.apache.hadoop:hadoop-common:2.7.2" in the 
Dependencies section of interpreter setting on GUI. But jdbc interpreter 
supposed to work without asking user hadoop-common dependency.

Got it, makes perfect sense! 

Do you think we should add a comment in there, explaining that 
compatibility is the reason for such decoding? I feel like this might help 
future contributors to see how to deal with such compatibility issue.

Other then that - it looks great to me, thanks again for fixing! It shall 
be ready to merge to master right after that, if there is no further discussion.

Yes @bzz, I just deleted `if self.py3:` but not `img_str = 
img_str.decode('ascii')` (it is in line 173), which means it will be executed 
for both Python 2 and 3. Decoding bytes to string it necessary for Python 3 
because that version makes distinction between String and Bytes, which does not 
occur in Python 2.

Maybe, `img_str = img_str.decode('ascii')` should be in a separate line of 
code to be clear.

 Project: Zeppelin
  Issue Type: Improvement
Affects Versions: 0.6.1
 Environment: DEV
Reporter: Bhanuprakash Prathap


We know that Zeppelin has introduced shiro authentication with 0.6.0. Can this 
be used/enhanced to provide SSO/LDAP authentication with our organization LDAP 
Team? We are trying to achieve a common authentication methodology for members 
across the organization.

Any information/help to integrate Zeppelin with LDAP/SSO authentication would 
be great.

Note: Currently our ORG SSO Team default servers for providing SSO is WAS with 
IHS(IBM HTTP Server).

[GitHub] zeppelin issue #1315: [ZEPPELIN-530] Added changes for Credential Provider, ...

[rconline]

Github user rconline commented on the issue:

https://github.com/apache/zeppelin/pull/1315
  
@jongyoul let me try to take a step back and try to explain.

Zeppelin is going to be used for various use cases, some of which will 
involve HDFS - Hive/Spark/Phoenix/Hbase etc, some use cases will also need 
support for non-HDFS such as Postgres/Mysql etc. 

**Problem** - all of these end systems may require users to store 
passwords. Currently in zeppelin there are two locations for storing these 
passwords - 1. shiro.ini for AD passwords and 2. interpreter.json for the rest 
of the data systems. These passwords are stored in clear text as of now. 

**Solution** - Encrypt the password and store in a file that can be read 
only at runtime, by zeppelin process to connect successfully. Question is 
where? Either on the zeppelin host system or hdfs where big-data users are akin 
to storing passwords. JCEKS is a java supported concept and has worked well for 
most users, and therefore can be used. Creating a .jceks file is possible on a 
host, 
`jceks://file/tmp/test.jceks`, whereas on HDFS the user may have to connect 
to hdfs and then create the file such as 
`jceks://h...@nn1.example.com/my/path/test.jceks`, when the password is being 
stored on hdfs. 

At this point in time we have solved the problem for not storing passwords 
in Shiro.ini, which can be stored at the zeppelin host itself. However we have 
to improve this solution and make it work for the rest of the use cases and 
that's where Credential API comes into play. 

Credential API is a generic solution which allows users to create password 
files for both of the cases - on the host and hdfs. Needless to point out that 
this has been used across Knox, which is a good standard for security. 

Please let me know if this makes sense, or if you have any more questions.

[GitHub] zeppelin issue #1315: [ZEPPELIN-530] Added changes for Credential Provider, ...

[jongyoul]

Github user jongyoul commented on the issue:

https://github.com/apache/zeppelin/pull/1315
  
@rconline It's not clear for me. Do you tell me that users store their 
Hive, Hbase passwords in HDFS? Or does this support reading `jceks` from HDFS? 
In your description, this PR is for encrypting the plain text password. I don't 
know what the relationship is from HDFS. I think you should describe why you 
must use hadoop-common in details.

@jongyoul this work is currently solving for AD, but is not limited to it. 
Going forward users may choose to store their Hive, Hbase and other data system 
passwords. These passwords as conventions get stored on HDFS, where we will 
need a simplified, credential API, and therefore the choice is to use the 
credential API. Also this is pretty standard implementation in the Big Data 
world.

@prabhjyotsingh  I agree @echarles's idea. Interpreter tries to find hadoop 
dependencies first and if it passes, it uses `doAs`. Otherwise, let's talk 
about how to do it.  How do you think of it?

Github user jongyoul commented on the issue:

@rconline Thanks for explaining it. I've researched the `jceks`. AFAIK, it 
doesn't need hadoop-common dependencies. It's included by java.security by 
default. Can you remove hadoop-common and support `jceks`? I've googled it and 
found some examples. Basically, `jceks` would be a good candidate for making 
password secured.

[GitHub] zeppelin issue #1302: [ZEPPELIN-1306] Interpreter restarts on a note.

[AhyoungRyu]

Github user AhyoungRyu commented on the issue:

https://github.com/apache/zeppelin/pull/1302
  
@astroshim I've also thought the interpreter `restart` button in separated 
page quite uncomfortable. This PR can be a good start for the better UX i think 
:)
I tested your patch and it almost works well except one thing. 

>can only restart `scoped` and `isolated` interpreter.

Since you said like above in the description,  I edited `Spark` interpreter 
as `shared` mode in the interpreter menu and restarted with your new 
interpreter binding UI. I expected it failed with some error messages, but it 
restarted. Did I miss sth?

[jira] [Created] (ZEPPELIN-1354) Inject Services

[Eric Charles (JIRA)]

 Summary: Inject Services
 Key: ZEPPELIN-1354
 URL: https://issues.apache.org/jira/browse/ZEPPELIN-1354
 Project: Zeppelin
  Issue Type: Improvement
Reporter: Eric Charles
Assignee: Eric Charles


Services like authentication, authorization, security filters... should be 
injected rather than manually instanciated.

This will allow to give central + finer control and abstracting the functionaly 
in interface.

For this, I propose to use Guice as injection framework.

There actually are tests, but we do not have CI profiles with both Python2 
and Python3 yet. I think, I will take a look into creating one soon. 
Though @felixcheung is right, there are no Integration Tests for Python 
interpreter yet, the one that might verify that image appears in the paragraph. 
It would be nice to have one, but I guess it's a bit out of scope for this PR.

Github user felixcheung commented on the issue:

https://github.com/apache/zeppelin/pull/1284
  
As before, I think it will be more intuitive if in a paragraph, the user 
types:
```
%hadoop1
spark.
```
And to autocomplete and the popups says `hadoop1`?
Yes, I agree the completion is for "Spark stuff" but completion result 
might include items that are interpreter instance/state specific things, like 
local variables and so on?

That said, I don't feel strongly about this so I'll let others to comment.

[jira] [Created] (ZEPPELIN-1353) java.lang.VerifyError for spark interpreter

[hy5446 (JIRA)]

hy5446 created ZEPPELIN-1353:


 Summary: java.lang.VerifyError for spark interpreter
 Key: ZEPPELIN-1353
 URL: https://issues.apache.org/jira/browse/ZEPPELIN-1353
 Project: Zeppelin
  Issue Type: Bug
Reporter: hy5446


I have just cloned the git repo and compiled zeppelin to try it out. 
Loosely following this guide: 
https://www.mapr.com/blog/building-apache-zeppelin-mapr-using-spark-under-yarn

git rev-parse HEAD
54d435303c58739de6ca57144f63532637cd291e

mvn package -Pbuild-distr -Pmapr51 -Pyarn -Pspark-1.6 -Pscala-2.10 -Phadoop-2.7 
-Pscalding -DskipTests

then, i edited the spark interpreter to change "master" to "yarn"
I tried a very simple program in my notebook:

%spark 
println("hello");

which failed and in the log I see this exception (see below)
can you help me to figure out what's wrong?

Subject: RE: Issues in Zeppelin 0.6.0

We upgraded Ambari Cluster  while we were working with Zeppelin 0.5.6. At that 
point, we were using Spark 1.5.2. After the upgrade of Ambari, the Spark 
version got upgraded to 1.6. Post that we upgraded Zeppelin to 0.6.0.

Hi,

Actually, when we worked on Zeppelin 0.5.6, we used to use sqlContext itself 
for reading hive files, registering spark dataframes as temp tables and 
eventualy processing queries on the temp tables.

The issue which I am facing on Zeppelin 0.6.0 right now  is that even though I 
am able to execute “SELECT”  query on the temptables but I am not able to 
execute DDL statements like Create/Drop tables using temptables derived from 
the hive files.

To elaborate it further:
When I write the following codes, they work fine. PFB the sample codes:

  *   sqlContext.sql(“select * from table name”)
  *   sqlContext.sql(“Select count(column_name) from table_name”)
But when I write the following codes, it fails to execute:

  *   sqlContext.sql(“create tablename as select * from tablename_1”)
  *   sqlContext.sql(“drop if exists tablename”)

I am getting the error : java.lang.RuntimeException: [1.1] failure: ``with'' 
expected but identifier drop found :
I even tried using sql interpreter.

PFB the code for it:
%sql
Drop if exists tablename
I am getting the same error again: : java.lang.RuntimeException: [1.1] failure: 
``with'' expected but identifier drop found :

Thanks a lot for being so responsive. Hope to fix this issue soon with your 
help.

Thanks and Regards,

Sorry, you should use sqlContext

Hi,

We tried “hiveContext” instead of “HiveContext” but it didn’t work out.
Please find below the code and the error log:

import org.apache.spark.sql.hive.HiveContext
val df_test_hive = hiveContext.read.parquet("/location/hivefile")

import org.apache.spark.sql.hive.HiveContext
:67: error: not found: value hiveContext
val df_test_hive = hiveContext.read.parquet("/location/hivefile")

It seems hiveContext is not an object of HiveContext package.
Could you please suggest if there is any other way out?

Whatever `su` or `ssh` is used, I feel the main trick is the user 
provisioning on the host running the interpreter. Until now, the shiro 
authentication system had no impact on the user provisioning. This PR changes 
this.

I guess we all agree and are aware that adding user `foo` to shiro.ini, and 
enabling impersonation, will require to run `adduser foo` manually.

We should make this clear in the doc but also stress it in the UI (with a 
hover, or a clear text/link near the  User Impersonate.
