To send messages from {{% param "product.abbrev" %}} to HDFS, complete the following steps.

Steps:

  1. {{< include-headless "chunk/para-java-requirements.md" >}}

  2. Download the Hadoop Distributed File System (HDFS) libraries (version 2.x) from http://hadoop.apache.org/releases.html.

  3. Extract the HDFS libraries into a temporary directory, then collect the various .jar files into a single directory (for example, /opt/hadoop/lib/) where {{% param "product.abbrev" %}} can access them. You must specify this directory in the {{% param "product.abbrev" %}} configuration file. The files are located in the various lib directories under the share/ directory of the Hadoop release package. (For example, in Hadoop 2.7, required files are common/hadoop-common-2.7.0.jar, common/libs/\*.jar, hdfs/hadoop-hdfs-2.7.0.jar, hdfs/lib/\*, but this may change between Hadoop releases, so it is easier to copy every .jar file into a single directory.
