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.

Separatordelete-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
