HBase Link Parameters
- MRS HBase
- FusionInsight HBase
- Apache HBase
Do not change the password or user when the job is running. If you do so, the password will not take effect immediately and the job will fail.
MRS HBase
When connecting CDM to HBase of MRS, configure the parameters as described in Table 1.
-
MRS clusters whose Kerberos encryption type is aes256-sha2,aes128-sha2 are not supported, and only MRS clusters whose Kerberos encryption type is aes256-sha1,aes128-sha1 are supported.
- Before creating an MRS link, you need to add an authenticated Kerberos user on MRS and log in to the MRS management page to change the initial password. Then use the new user to create an MRS link.
- To connect to an MRS 2.x cluster, create a CDM cluster of version 2.x first. CDM 1.8.x clusters cannot connect to MRS 2.x clusters.
-
If the connection fails after you select a cluster, check whether the MRS cluster can communicate with the CDM instance which functions as the agent. They can communicate with each other in the following scenarios:
- If the CDM cluster in the DataArts Studio instance and the MRS cluster are in different regions, a public network or a dedicated connection is required. If the Internet is used for communication, ensure that an EIP has been bound to the CDM cluster, and the MRS cluster can access the Internet and the port has been enabled in the firewall rule.
- If the CDM cluster in the DataArts Studio instance and the MRS cluster are in the same region, VPC, subnet, and security group, they can communicate with each other by default. If they are in the same VPC but in different subnets or security groups, you must configure routing rules and security group rules. For details about how to configure routing rules, see Configuring Routing Rules. For details about how to configure security group rules, see Configuring Security Group Rules.
- The MRS cluster and the DataArts Studio workspace belong to the same enterprise project. If they do not, you can modify the enterprise project of the workspace.
If an agent is connected to multiple MRS clusters and one of the MRS clusters is deleted or abnormal, connections to the other MRS clusters will be affected. Therefore, you are advised to connect an agent to only one MRS cluster.
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 |
mrs_hbase_link |
Manager IP |
Floating IP address of MRS Manager. Click Select next to the Manager IP text box to select an MRS cluster. CDM automatically fills in the authentication information.
NOTE:
DataArts Studio does not support MRS clusters whose Kerberos encryption type is aes256-sha2,aes128-sha2, and only supports MRS clusters whose Kerberos encryption type is aes256-sha1,aes128-sha1. |
127.0.0.1 |
Username |
If Authentication Method is set to KERBEROS, you must provide the username and password used for logging in to MRS Manager. If you need to create a snapshot when exporting a directory from HDFS, the user configured here must have the administrator permission on HDFS.
To create a data connection for an MRS security cluster, do not use user admin. The admin user is the default management page user and cannot be used as the authentication user of the security cluster. You can create an MRS user and set Username and Password to the username and password of the created MRS user when creating an MRS data connection.
