This Processor polls HBase for any records in the specified table. The processor keeps track of the timestamp of the cells that it receives, so that as new records are pushed to HBase, they will automatically be pulled. Each record is output in JSON format, as {“row”: “<row key>”, “cells”: { “<column 1 family>:<column 1 qualifier>”: “<cell 1 value>”, “<column 2 family>:<column 2 qualifier>”: “<cell 2 value>”, … }}. For each record received, a Provenance RECEIVE event is emitted with the format hbase://<table name>/<row key>, where <row key> is the UTF-8 encoded value of the row’s key.

Table Name The name of the HBase Table to put data into
Columns A comma-separated list of "<colFamily>:<colQualifier>" pairs to return when scanning. To return all columns for a given family, leave off the qualifier such as "<colFamily1>,<colFamily2>".
Filter Expression An HBase filter expression that will be applied to the scan. This property can not be used when also using the Columns property.
Initial Time Range None * None</br> * Current Time The time range to use on the first scan of a table. None will pull the entire table on the first scan, Current Time will pull entries from that point forward.
