Currently, I using the JDBC Driver to connect external MSSQL for kylin
The configuration for kylin.properties as below:

And I managed to load the external MS SQL tables as below:
!image-2021-04-23-10-35-29-989.png!
However, when I want to build a cube for this external MS SQL, I encounter
credential error on the step 1 “Sqoop To Flat Hive Table” as below:

So, I copy out the sqoop commond an run individually in the kylin env:
sqoop import -Dorg.apache.sqoop.splitter.allow_text_splitter=true
-Dmapreduce.job.queuename=default --connect
"jdbc:sqlserver://xxx.xxx.xxx.xx7:1433;database=xxS" --driver
com.microsoft.sqlserver.jdbc.SQLServerDriver --username xxxxxxxt --password
"xxxxxxxd" --query "SELECT [BKOR_BIW_DETAILS_SUMMARY].[VOT] as
[BKOR_BIW_DETAILS_SUMMARY_VOT] ,[BKOR_BIW_DETAILS_SUMMARY].[PROJECT_NAME] as
[BKOR_BIW_DETAILS_SUMMARY_PROJECT_NAME]
,[BKOR_BIW_DETAILS_SUMMARY].[CONTINGENT] as
[BKOR_BIW_DETAILS_SUMMARY_CONTINGENT]
,[BKOR_BIW_DETAILS_SUMMARY].[DEPARTMENT_LONG] as
[BKOR_BIW_DETAILS_SUMMARY_DEPARTMENT_LONG]
,[BKOR_BIW_DETAILS_SUMMARY].[CASH_FLOW] as [BKOR_BIW_DETAILS_SUMMARY_CASH_FLOW]

--target-dir

[dbo].[BKOR_BIW_DETAILS_SUMMARY] " --null-string '\\N' --null-non-string '\\N'

However, I faced same credential error as in kylin.
Therefore, I change the command with replace --password "xxxxxxxd" to –P, and
the command is running well as below:

Is that any configuration I miss out?
