Constructor Detail

LivyClientBuilder

public LivyClientBuilder()
                  throws IOException

Creates a new builder that will automatically load the default Livy and Spark configuration from the classpath.

Throws:

IOException - If an error occurred when reading from the config files.

LivyClientBuilder

public LivyClientBuilder(boolean loadDefaults)
                  throws IOException

Creates a new builder that will optionally load the default Livy and Spark configuration from the classpath. Livy client configuration is stored in a file called "livy-client.conf", and Spark client configuration is stored in a file called "spark-defaults.conf", both in the root of the application's classpath. Livy configuration takes precedence over Spark's (in case configuration entries are duplicated), and configuration set in this builder object will override the values in those files.

Parameters:

loadDefaults - Whether to load configs from spark-defaults.conf and livy-client.conf if they are found in the application's classpath.

Throws:

IOException - If an error occurred when reading from the config files.
