How to check the Spark version

Question

as titled, how do I know which version of spark has been installed in the CentOS?

The current system has installed cdh5.1.0.

Answer 1

In Spark 2.x program/shell,

use the

spark.version  

Where spark variable is of SparkSession object

Using the console logs at the start of spark-shell

[root@bdhost001 ~]$ spark-shell
Setting the default log level to "WARN".
To adjust logging level use sc.setLogLevel(newLevel).

Without entering into code/shell

spark-shell --version

[root@bdhost001 ~]$ spark-shell --version
