This processor allows the user to delete individual HBase cells by specifying one or more lines in the flowfile content that are a sequence composed of row ID, column family, column qualifier and associated visibility labels if visibility labels are enabled and in use. A user-defined separator is used to separate each of these pieces of data on each line, with :::: being the default separator.

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 Implementations: HBase_2_ClientService HBase_1_1_2_ClientService | Specifies the Controller Service to use for accessing HBase. | |
| Table Name | Table Name | The name of the HBase Table. Supports Expression Language: true (will be evaluated using flow file attributes and variable registry) | ||
| Separator | delete-hbase-cell-separator | :::: | Each line of the flowfile content is separated into components for building a delete using thisseparator. It should be something other than a single colon or a comma because these are values that are associated with columns and visibility labels respectively. To delete a row with ID xyz, column family abc, column qualifier def and visibility label PII&PHI, one would specify xyz::::abc::::def::::PII&PHI given the default value Supports Expression Language: true (will be evaluated using flow file attributes and variable registry) |
