Description:

This processor writes FlowFiles to an HDFS cluster. It will create directories in which to store files as needed based on the Directory property.

When files are written to HDFS, the file's owner is the user identity of the NiFi process, the file's group is the group of the parent directory, and the read/write/execute permissions use the default umask. The owner can be overridden using the Remote Owner property, the group can be overridden using the Remote Group property, and the read/write/execute permissions can be overridden using the Permissions umask property.

NOTE: This processor can change owner or group only if the user identity of the NiFi process has super user privilege in HDFS to do so.

NOTE: The Permissions umask property cannot add execute permissions to regular files.
