+You will also need to provide a JDBC driver that is compatible with Redshift. Amazon recommend that you use [their driver](http://docs.aws.amazon.com/redshift/latest/mgmt/configure-jdbc-connection.html), which is distributed as a JAR that is hosted on Amazon's website. This library has also been successfully tested using the Postgres JDBC driver.
- - For Scala 2.10: use the coordinate `com.github.databricks:spark-redshift_2.10:master-SNAPSHOT`
- - For Scala 2.11: use the coordinate `com.github.databricks:spark-redshift_2.11:master-SNAPSHOT`
+**Note on Hadoop versions**: This library depends on [`spark-avro`](https://github.com/databricks/spark-avro), which should automatically be downloaded because it is declared as a dependency. However, you may need to provide the corresponding `avro-mapred` dependency which matches your Hadoop distribution. In most deployments, however, this dependency will be automatically provided by your cluster's Spark assemblies and no additional action will be required.
+**Note on Amazon SDK dependency**: This library declares a `provided` dependency on components of the AWS Java SDK. In most cases, these libraries will be provided by your deployment environment. However, if you get ClassNotFoundExceptions for Amazon SDK classes then you will need to add explicit dependencies on `com.amazonaws.aws-java-sdk-core` and `com.amazonaws.aws-java-sdk-s3` as part of your build / runtime configuration. See the comments in `project/SparkRedshiftBuild.scala` for more details.

-As we discussed earlier Spark SQL will search for a class named `DefaultSource` in the data source's package, `com.databricks.spark.redshift`. The `DefaultSource` class implements the `RelationProvider` trait, which provides the default load functionality for the library. The `RelationProvider` trait provides methods which consume the user-provided configuration parameters and return instances of `BaseRelation`, which `spark-redshift` implements using class `com.databricks.spark.redshift.RedshiftRelation`.

-The `com.databricks.spark.redshift.RedshiftRelation` class is responsible for providing an `RDD` of `org.apache.spark.sql.Row` which backs the `org.apache.spark.sql.DataFrame` instance.
