Link to HBase¶

Description¶

By creating an HBase link, you can extract data from or load data to HBase of MRS, FusionInsight HD, and Apache Hadoop.

Sample Link¶

  "links": [
    {
      "link-config-values": {
        "configs": [
          {
            "inputs": [

Link Parameters¶

Parameter

Mandatory

Type

Description

linkConfig.hbaseType

Yes

Enumeration

HBase type. The options are as follows:

  • CloudTable: link to CloudTable Service (CloudTable)

  • MRS: link to HBase of MRS

  • FusionInsight HD: link to HBase of FusionInsight HD

  • Apache Hadoop: link to HBase of Apache Hadoop

linkConfig.uri

No

String

NameNode URI required for the link to Apache Hadoop. The format is ip:port.

llinkConfig.host

No

String

IP address of Manager required for the link to MRS or FusionInsight HD

linkConfig.port

No

String

Port number of Manager required for the link to FusionInsight HD

linkConfig.casPort

No

String

Port number of CAS Server that connects to FusionInsight HD required for the link to FusionInsight HD

linkConfig.hBaseVersion

Yes

Enumeration

HBase version

  • HBASE_1_X

  • HBASE_2_X

linkConfig.user

No

String

Username for logging in to Manager. This parameter is not required if the cluster configuration is used.

linkConfig.password

No

String

Password for logging in to Manager. This parameter is not required if the cluster configuration is used.

linkConfig.authType

No

Enumeration

Authentication method. The options are as follows:

  • Simple: for non-security mode

  • Kerberos: for security mode

linkConfig.principal

No

String

Account principal required for Kerveros authentication. You can contact the administrator to obtain the account.

linkConfig.keytab

No

FileContent

Local absolute path of the keytab file required for Kerveros authentication. You can also contact the administrator to obtain the file.

linkConfig.serviceType

No

String

Service type Currently, HDFS and HBase are supported.

linkConfig.runMode

No

Enumeration

This parameter is used only when the HBase version is HBase_2_X. Possible values are:

  • EMBEDDED: The link instance runs with CDM. This mode delivers better performance.

  • STANDALONE: The link instance runs in an independent process. If CDM needs to connect to multiple Hadoop data sources (MRS, Hadoop, or CloudTable) with both Kerberos and Simple authentication methods, STANDALONE is used.

    If STANDALONE is selected, CDM can migrate data between HDFSs of multiple MRS clusters.

    If a CDM cluster connects to two or more clusters with Kerberos authentication enabled and the same realm, only one cluster can be connected in EMBEDDED mode, and the other clusters must be connected in STANDALONE mode.

linkConfig.properties

No

Map

Properties. You can add configuration properties of the client. Each property must contain a name and a value.
