Link to CloudTable

When connecting CDM to CloudTable, configure the parameters as described in Table 1.

Table 1 Parameter description

Parameter

Description

Example Value

Name

Link name, which should be defined based on the data source type, so it is easier to remember what the link is for

cloudtable_link

ZK Link

Obtain this parameter value from the cluster management page of CloudTable.

cloudtable-cdm-zk1.cloudtable.com:2181,cloudtable-cdm-zk2.cloudtable.com:2181

IAM Authentication

If IAM authentication is enabled for the CloudTable cluster to be connected, set this parameter to Yes. Otherwise, set this to No.

If you select Yes, enter the username, AK, and SK.

No

Username

Username used for accessing the CloudTable cluster

admin

AK

AK for accessing the CloudTable cluster.

If you have not created access keys for your account, create them as described in (Optional) Obtaining the Authentication Information.

-

SK

SK for accessing the CloudTable cluster. For details about how to obtain the SK, see the description for AK.

-

Run Mode

Run mode of the HBase link. This parameter is used only when the HBase version is HBASE_2_X.

  • 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 modes, select STANDALONE or configure different agents.

    Note: The STANDALONE mode is used to solve the version conflict problem. If the connector versions of the source and destination ends of the same link are different, a JAR file conflict occurs. In this case, you need to place the source or destination end in the STANDALONE process to prevent the migration failure caused by the conflict.

  • Agent: The link instance runs on an agent.

EMBEDDED
