You can see in the tree what's pulling in 2.11. Your option then will be to either shade them and add an explicit dependency on 2.10.5 in your pom. Alternatively, you can explore upgrading your project to 2.11 (which will require using a 2_11 build of spark)

You’re right. I don’t see anything but 2.11 being pulled in. Do you know where I can change this?

Sorry for my persistence, but did you actually run "mvn dependency:tree -Dverbose=true"? And did you see only scala 2.10.5 being pulled in?

It’s still the same. Do you have any other ideas?

Did you check the actual maven dep tree? Something might be pulling in a different version. Also, if you're seeing this locally, you might want to check which version of the scala sdk your IDE is using

Hi Asher,

I modified the pom to be the same Spark (1.6.0), HBase (1.2.0), and Java (1.8) version as our installation. The Scala (2.10.5) version is already the same as ours. But I’m still getting the same error. Can you think of anything else?

That looks like a scala version mismatch. Have you checked your dep tree?

Can you give me some sample code? I can’t get mine to work.

import org.apache.spark.sql.{SQLContext, _}

It gives me this error.

If you can please help, I would be grateful.

Does anyone know how to backport the HBase Spark module to HBase 1.2.0? I tried to build it from source, but I cannot get it to work.
