Hadoop Dependencies Installation
Starting with version 3.2, Spark has reduced the number of Hadoop libraries which are part of the downloadable Spark
distribution. Unfortunately, some of the libraries which have been removed are required by some Flowman plugins (for
example the S3 and Delta plugin need the
hadoop-commons library). Since at the same time Flowman will for good
reasons not include these missing libraries, you have to install these yourself and put them into the
In order to simplify getting the appropriate Hadoop libraries and placing them into the correct Spark directory,
Flowman provides a small script called
install-hadoop-dependencies, which will download and install the missing
export SPARK_HOME=your-spark-home cd $FLOWMAN_HOME bin/install-hadoop-dependencies
Note that you need to have appropriate write permissions into the
$SPARK_HOME/jars directory, so you possibly need
to execute this with super-user privileges.
Also note that this script will download and install the Hadoop libraries with the build version of Flowman, not the version of the already existing Hadoop libraries.
