+=== HDFS Content Repository Properties
+
+This content repository uses the Hadoop FileSystem API to store FlowFile content. Because of this, it can be used to store content on the local disk and/or in one or more distinct HDFS clusters. It also has four different operating modes which are described below in the `nifi.content.repository.hdfs.operating.mode` property.
+
+All of the properties defined above (see <<file-system-content-repository-properties,File System Content Repository Properties>>) still apply. Only HDFS-specific properties are listed here. 
+
+The equivalent default local content repository directory would be specified with:
+`nifi.content.repository.directory.default=file:content_repository`
+
+An HDFS content repository directory would be specified with:
+`nifi.content.repository.directory.default=hdfs://localhost:9000/content_repository`
+
+Example Minimal Configuration:
+`nifi.content.repository.implementation=org.apache.nifi.hdfs.repository.HdfsContentRepository`
+`nifi.content.repository.hdfs.core.site=./conf/core-site.xml`
+
+|====
+|*Property*|*Description*
+|`nifi.content.repository.implementation`|Value should be: `org.apache.nifi.hdfs.repository.HdfsContentRepository`
+|`nifi.content.repository.hdfs.core.site`|The default Hadoop `core-site.xml` file to configure file systems with. +
+
+	*NOTE:* This isn't actually required as long as each location specifies its own core.site.xml, however each directory is required to have a `core-site.xml` defined either with this property, or as described below.
