HDFS NAR Provider

This implementation is capable of downloading NAR files from an HDFS file system.

The value of the nifi.nar.library.provider.<providerName>.implementation must be org.apache.nifi.nar.hadoop.HDFSNarProvider. The following further properties are defined by the provider:

Name	Description
resources	List of HDFS resources, separated by comma.
source.directory	The source directory of NAR files within HDFS. Note: the provider does not check for files recursively.
storage.location	Optional. If set the storage location defined in the core-site.xml will be overwritten by this value.
kerberos.principal	Optional. Kerberos principal to authenticate as.
kerberos.keytab	Optional. Kerberos keytab associated with the principal.
kerberos.password	Optional. Kerberos password associated with the principal.

Example configuration:

nifi.nar.library.provider.hdfs1.implementation=org.apache.nifi.nar.hadoop.HDFSNarProvider
nifi.nar.library.provider.hdfs1.resources=/etc/hadoop/core-site.xml
nifi.nar.library.provider.hdfs1.source.directory=/customNars

nifi.nar.library.provider.hdfs2.implementation=org.apache.nifi.nar.hadoop.HDFSNarProvider
nifi.nar.library.provider.hdfs2.resources=/etc/hadoop/core-site.xml
nifi.nar.library.provider.hdfs2.source.directory=/other/dir/for/customNars
