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.
