Error:scalac: bad symbolic reference. A signature in SQLContext.class refers to type Logging in package org.apache.spark which is not available - scala

Question

When I complied a scala file used IntelliJ IDEA, the following error showed.
Error:scalac: bad symbolic reference. A signature in SQLContext.class refers to type Logging in package org.apache.spark which is not available.
It may be completely missing from the current classpath, or the version on
the classpath might be incompatible with the version used when compiling SQLContext.class.
Attention: the error happened when I add the spark-sql into the pom.xml file. Is it the version problem?
my pom.xml is：

Answer 1

Please use the same version of spark for all the dependencies.
<dependency>
<groupId>org.apache.spark</groupId>
<artifactId>spark-core_2.10</artifactId>
<version>2.1.0</version>
</dependency>
Replace this with
<dependency>
<groupId>org.apache.spark</groupId>
<artifactId>spark-core_2.10</artifactId>
<version>1.6.2</version>
</dependency>
Or you can use Spark 2.1.0 in all dependencies
