java.sql.SQLException: Method not supported when 'nulls' in resulset #7

Closed Worvast closed 8 years ago

Worvast commented 9 years ago

Hi, we has RImpala version 0.1.6 and we receive this error:

Error in .jcall("RJavaTools", "Ljava/lang/Object;", "invokeMethod", cl,  : 
  java.sql.SQLException: Method not supported

When try to make, for example, this query with nulls in some rows:

age_group <- rimpala.query(Q="select nom, type from aa_lc_pp.basic")

Simple query working in Hue, but if we not put 'where type is not null' the query show this error.

Any ideas about where we should look to solve this problem?

I cant create other branch/pull request to talk about fixed, i create a fork and modify the code for fix nulls problems in Java, build.sh script for fix routes and delete unnecesary files, you can see it in:
