Re: [SparkSQL] Convert JavaSchemaRDD to SchemaRDD

2014-10-16 Thread Cheng Lian
Why do you need to convert a JavaSchemaRDD to SchemaRDD? Are you trying 
to use some API that doesn't exist in JavaSchemaRDD?

Finally I find this solution:

 jrdd.registerTempTable(transform_tmp)
 jrdd.sqlContext.sql(select * from transform_tmp)
/code
/pre



Could Any One tell me that: Is it a good idea for me to *use catalyst as
DSL's execution engine?*

I am trying to build a DSL, And I want to confirm this.

I'm trying to give API interface to Java users. And I need to accept their
JavaSchemaRDDs, and convert it to SchemaRDD for Scala users.
