Properties:

In the list below, the names of required properties appear in bold. Any other properties (not in bold) are considered optional. The table also indicates any default values, and whether a property supports the NiFi Expression Language.

Display NameAPI NameDefault ValueAllowable ValuesDescription
HostnameHostnameThe fully qualified hostname or IP address of the remote system
Supports Expression Language: true (will be evaluated using flow file attributes and Environment variables)
PortPort22The port that the remote system is listening on for file transfers

PasswordPasswordPassword for the user account
Sensitive Property: true
Supports Expression Language: true (will be evaluated using flow file attributes and Environment variables)
Private Key PathPrivate Key PathThe fully qualified path to the Private Key file

This property requires exactly one file to be provided..

Supports Expression Language: true (will be evaluated using flow file attributes and Environment variables)
Private Key PassphrasePrivate Key PassphrasePassword for the private key
Sensitive Property: true
Supports Expression Language: true (will be evaluated using flow file attributes and Environment variables)
Remote PathRemote PathThe path on the remote system from which to pull or push files
Supports Expression Language: true (will be evaluated using flow file attributes and Environment variables)
Create DirectoryCreate Directoryfalse
  • true
  • false
Specifies whether or not the remote directory should be created if it does not exist.
Disable Directory ListingDisable Directory Listingfalse
  • true
  • false
If set to 'true', directory listing is not performed prior to create missing directories. By default, this processor executes a directory listing command to see target directory existence before creating missing directories. However, there are situations that you might need to disable the directory listing such as the following. Directory listing might fail with some permission setups (e.g. chmod 100) on a directory. Also, if any other SFTP client created the directory after this processor performed a listing and before a directory creation request by this processor is finished, then an error is returned because the directory already exists.
Batch SizeBatch Size500The maximum number of FlowFiles to send in a single connection
Connection TimeoutConnection Timeout30 secAmount of time to wait before timing out while creating a connection
Data TimeoutData Timeout30 secWhen transferring a file between the local and remote system, this value specifies how long is allowed to elapse without any data being transferred between systems
Conflict ResolutionConflict ResolutionNONE
  • REPLACE
  • IGNORE
  • RENAME
  • REJECT
  • FAIL
  • NONE
Determines how to handle the problem of filename collisions
Reject Zero-Byte FilesReject Zero-Byte Filestrue
  • true
  • false
Determines whether or not Zero-byte files should be rejected without attempting to transfer
Dot RenameDot Renametrue
  • true
  • false
If true, then the filename of the sent file is prepended with a "." and then renamed back to the original once the file is completely sent. Otherwise, there is no rename. This property is ignored if the Temporary Filename property is set.
Temporary FilenameTemporary FilenameIf set, the filename of the sent file will be equal to the value specified during the transfer and after successful completion will be renamed to the original filename. If this value is set, the Dot Rename property is ignored.
Supports Expression Language: true (will be evaluated using flow file attributes and Environment variables)
Host Key FileHost Key FileIf supplied, the given file will be used as the Host Key; otherwise, if 'Strict Host Key Checking' property is applied (set to true) then uses the 'known_hosts' and 'known_hosts2' files from ~/.ssh directory else no host key file will be used

This property requires exactly one file to be provided..
Last Modified TimeLast Modified TimeThe lastModifiedTime to assign to the file after transferring it. If not set, the lastModifiedTime will not be changed. Format must be yyyy-MM-dd'T'HH:mm:ssZ. You may also use expression language such as ${file.lastModifiedTime}. If the value is invalid, the processor will not be invalid but will fail to change lastModifiedTime of the file.
Supports Expression Language: true (will be evaluated using flow file attributes and Environment variables)
PermissionsPermissionsThe permissions to assign to the file after transferring it. Format must be either UNIX rwxrwxrwx with a - in place of denied permissions (e.g. rw-r--r--) or an octal number (e.g. 644). If not set, the permissions will not be changed. You may also use expression language such as ${file.permissions}. If the value is invalid, the processor will not be invalid but will fail to change permissions of the file.
Supports Expression Language: true (will be evaluated using flow file attributes and Environment variables)
Remote OwnerRemote OwnerInteger value representing the User ID to set on the file after transferring it. If not set, the owner will not be set. You may also use expression language such as ${file.owner}. If the value is invalid, the processor will not be invalid but will fail to change the owner of the file.
Supports Expression Language: true (will be evaluated using flow file attributes and Environment variables)
Remote GroupRemote GroupInteger value representing the Group ID to set on the file after transferring it. If not set, the group will not be set. You may also use expression language such as ${file.group}. If the value is invalid, the processor will not be invalid but will fail to change the group of the file.
Supports Expression Language: true (will be evaluated using flow file attributes and Environment variables)
Strict Host Key CheckingStrict Host Key Checkingfalse
  • true
  • false
Indicates whether or not strict enforcement of hosts keys should be applied
