Chapter 7. Adding Libraries to Spark
To use a custom library with a Spark application (a library that is not available in Spark
by default, such as a compression library or Magellan), use one of the following two spark-submit script
options:
The
--jarsoption transfers associated jar files to the cluster.The
--packagesoption pulls directly from Spark packages. This approach requires an internet connection.
For example, to add the LZO compression library to Spark using the --jars
option:
spark-submit --driver-memory 1G --executor-memory 1G --master yarn-client --jars /usr/hdp/2.3.0.0-2557/hadoop/lib/hadoop-lzo-0.6.0.2.3.0.0-2557.jar test_read_write.py
For more information about the two options, see Advanced Dependency Management in the Apache Spark "Submitting Applications" document.
