Run Queries with Apache SHARK on Mac OSX

Question

I am having trouble running queries with Shark locally on Mac OSX 10.8. I am trying to run some test queries on data stored in Hive. I am using Scala 2.9.3 and Hive 0.9.0 and both seem to be running fine. The Hive database is using MySQL to store metadata.

I can start up Shark fine. I can see all my databases in Hive in the Shark console. I can switch to the desired database. But when I try to query data I get errors.

The simple query looks like this:

select * from table limit 100;

The error looks like this:

Answer 1

this looks like a recent addition to Shark code, https://github.com/amplab/shark/pull/140/files perhaps wasn't tested with Hive 0.9?

current HadoopShims.java does have the isLocalMode() , but the Hive 0.9 HadoopShims.java does not have the isLocalMode() method.

I would recommend using at least Hive 0.10, or even better a recent 0.12 if you can.
