Yes, actually there is NPE throw by JdbcExplorer, but it is not the first 
exception which related to JdbcExplorer, and that previous exception  should be 
the root cause. You may search "jdbc.extensible" or "JdbcSource" in kylin.log 
and you will find more information. I guess maybe your jdbc information like 
user/password/url is not configured in correct way.



Could you please find it and share with us? And it is OK if you send my the 
whole log file and I will check it.

Hi Andrey,
Firstly, thank you for your testing on our build, I have some question to ask:

  1.  When you set kylin.source.default=16, you said you found “Oops… Failed to 
take action.”, did you see what the exception kylin throw? Could you please 
show us error message in kylin.log? Our patch work when 
kylin.source.default=16, so the error message throw by kylin when you set it to 
8 is not what we care in this issue/PR. So the important things is what 
occurred when you see “Oops… Failed to take action.”
  2.  If you could provided more detail about you related config, maybe I can 
find something useful.

主题: Re: Kylin to PostgreSQL Error in Cube build Step 1

Hello, Sir.
I’ve installed the Kylin binary you’ve provided. Also I’ve prepared data tables 
that you used to test you build https://github.com/apache/kylin/pull/902 .
If I set a property kylin.source.default=16 and click on Load Table Metadata 
From Tree, I got an error: “Oops… Failed to take action.”
So, I was forced to use kylin.source.default=8. I prepared model and cube just 
like you, but still got the error on the first step
My env:

•         PostgreSQL 9.5.20

•         cdh 5.16.2

•         Kylin build from master branch
Here is log:

Hi Molotov,
 The PR is under review and test, and In my side it is OK, you can check the 
test with screenshot at page (https://github.com/apache/kylin/pull/902) to see 
if it is tested well. If you want to test it at your env, please let me know, 
and I will send the binary to you.

  Hello, thank you for your answer.
  I pulled the commit you provided and compiled jar file (two jar files, 
actually: kylin-source-jdbc-3.0.0-SNAPSHOT.jar and 
kylin-jdbc-3.0.0-SNAPSHOT.jar). Then for each of these files I did following: 
renamed it and put it instead of existing kylin-jdbc-2.6.4.jar file in 
kylin/lib directory.
  But unfortunately this did help me resolve my problem with the backtick in 
SQL query.
  Is there any other way to get a proper query line for PostgreSQL or maybe I 
did something wrong? Thanks in advance.

Hi, Molotov, because postgresql's syntax and metadata have certain 
specialities, need to do some development work. PR 
https://github.com/apache/kylin/pull/747

Hello, everyone.
I’ve set up Kylin to access a PostgreSQL Database using JDBC as described in 
http://kylin.apache.org/docs/tutorial/setup_jdbc_datasource.html .
I’ve also set kylin.source.default=16 and kylin.source.hive.enable.quote=false
