回复：答复: error: object jblas is not a member of package org
Thanks for the tip, but my analytic queries work fine after my Scala script is pre-loaded. In my notebook, I just type in "%sql SQL-QUERY-STATEMENT", and it works fine. What exactly is %dep used for ? I never used this interpreter.

Thanks so much! It works fine as I expected.
Note that%dep interpreter should be used before %spark, %pyspark, %sql.

Run
//////////////////////////////////////////////////////////////////
%dep
z.load("org.scalanlp:jblas:1.2.1")
//////////////////////////////////////////////////////////////////
Out:
dep interpreter not found
Hi,
have you tried to load jblas library using %dep interpreter?
For example, you can try to run below:
```
%dep
z.load("org.scalanlp:jblas:1.2.1")
```
And then run
`import org.jblas.DoubleMatrix` in next paragraph.
If you want to know another way to load external library, please check "Dependency Management" section in https://zeppelin.incubator.apache.org/docs/0.6.0-incubating-SNAPSHOT/interpreter/spark.html
Hope this helps.

Posted by Mina Lee <mi...@apache.org>.
Purpose of %dep is loading external libraries to Zeppelin and distribute
them to workers.
For example, if your pre-loaded scala script needs to import spark-csv
library, you will need to run dep interpreter first as below prior to
running other scala, pyspark code:
%dep
z.load("com.databricks.spark-csv_2.10:1.3.0")
For your information, %dep interpreter load libraries only to %spark,
%pyspark but not to %sql. If you have *table* made with spark-csv library,
%spark
z.show(sqlc.sql("select * from table")
will work,
%sql
select * from table
won't work. I am currently working on this bug so patch will be made soon.
