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 Name	API Name	Default Value	Allowable Values	Description
HBase Client Service	HBase Client Service		Controller Service API: HBaseClientService Implementation: HBase_2_ClientService	Specifies the Controller Service to use for accessing HBase.
Table Name	Table Name			The name of the HBase Table to put data into Supports Expression Language: true (will be evaluated using flow file attributes and variable registry)
Row Identifier	Row Identifier			Specifies the Row ID to use when inserting data into HBase Supports Expression Language: true (will be evaluated using flow file attributes and variable registry)
Row Identifier Encoding Strategy	Row Identifier Encoding Strategy	String	String Binary	Specifies the data type of Row ID used when inserting data into HBase. The default behavior is to convert the row id to a UTF-8 byte array. Choosing Binary will convert a binary formatted string to the correct byte[] representation. The Binary option should be used if you are using Binary row keys in HBase
Column Family	Column Family			The Column Family to use when inserting data into HBase Supports Expression Language: true (will be evaluated using flow file attributes and variable registry)
Column Qualifier	Column Qualifier			The Column Qualifier to use when inserting data into HBase Supports Expression Language: true (will be evaluated using flow file attributes and variable registry)
Timestamp	timestamp			The timestamp for the cells being created in HBase. This field can be left blank and HBase will use the current time. Supports Expression Language: true (will be evaluated using flow file attributes and variable registry)
Batch Size	Batch Size	25		The maximum number of FlowFiles to process in a single execution. The FlowFiles will be grouped by table, and a single Put per table will be performed.

Name	Value	Description
visibility.<COLUMN FAMILY>	visibility label for <COLUMN FAMILY>	Visibility label for everything under that column family when a specific label for a particular column qualifier is not available. Supports Expression Language: true (will be evaluated using flow file attributes and variable registry)
visibility.<COLUMN FAMILY>.<COLUMN QUALIFIER>	visibility label for <COLUMN FAMILY>:<COLUMN QUALIFIER>.	Visibility label for the specified column qualifier qualified by a configured column family. Supports Expression Language: true (will be evaluated using flow file attributes and variable registry)
