HBase Sink
Plugin version: 2.11.0
Writes records to a column family in an HBase table with one record field mapping to the rowkey, and all other record fields mapping to table column qualifiers. This sink differs from the Table sink in that it does not use CDAP datasets, but writes to HBase directly.
The sink is used whenever you need to write to an HBase table in batch. For example, you may want to periodically dump the contents of a relational database into an HBase table.
Configuration
Property | Macro Enabled? | Description |
---|---|---|
Reference Name | No | Required. This will be used to uniquely identify this sink for lineage, annotating metadata, etc. |
HBase Table Name | Yes | Required. The name of the table to write to. Note: Prior to running the pipeline, this table should already exist. |
HBase Column Family | Yes | Required. The name of the column family to write to. |
Zookeeper Quorum String | Yes | Optional. The ZooKeeper quorum for the hbase instance you are writing to. This should be a comma-separated list of hosts that make up the quorum. You can find the correct value by looking at the |
Zookeeper Client Port | Yes | Optional. The client port used to connect to the ZooKeeper quorum. You can find the correct value by looking at the |

Parent Node of HBase in Zookeeper | No | Optional. The parent node of HBase in ZooKeeper. You can find the correct value by looking at the |
Output Schema | No | Required. Schema of records written to the table. Record fields map to row columns.
