DeleteHBaseCells

Description:

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.
