Container A container isolates CPU and memory resources on Java virtual machines (VMs). Core Node A core node in a MapReduce Service cluster processes data and stores process data in the HDFS.
For a remote node, write permission for the path is required. Updating Client Configurations (Version 2.x or Earlier) Method 1 (applicable to all versions) Log in to MRS Manager and choose Services. Click Download Client.
MS(MetaStore) This role can be deployed on the Master node only. Number of role instances to be deployed: 2 to 10 WH (WebHCat) This role can be deployed on the Master node only.
For example, a standard image Windows Server 2012 R2 Standard 64bit(40GB). For details about other parameters, see Purchasing an ECS .

(The Kerberos service is deployed on the master node by default. Therefore, the public IP address of the master node is used.) (Skip this step for common clusters with the Kerberos function disabled.)
Figure 1 HBase data model Phoenix is an intermediate structured query language (SQL) layer built on HBase. Phoenix provides a JDBC driver that can be embedded in a client.

After the MRS 2.1.0.11 patch is installed, log in to the standby Master node (Log in to MRS Manager.
Prerequisites The ECS corresponding to the server must be in the same VPC as the MRS cluster's Master node, and the Master node must be able to access the server's IP address and specified port.
Change the IP addresses of the kdc, admin_server, kpasswd_server, kdc_listen, kadmind_listen, and kpasswd_listen parameters in the krb5.conf file of the import example (if the cluster has only one master node, you do not need to modify the last three parameters).
You can log in to any Master node and obtain the values of the preceding parameters from the HBase client configuration (/opt/client/HBase/hbase/conf).
Prerequisites The ECS corresponding to the server must be in the same VPC as the MRS cluster's Master node, and the Master node must be able to access the server's IP address and specified port.
You can also refer to method 2 in Updating a Client (Versions Earlier Than 3.x) to perform operations in 1 to 4 for clusters whose versions are MRS 1.8.5 or later. Use the client on a Master node.
Notice: Before running commands, for example, the following two commands, on the server as user omm (the client must have the execute permission of user omm), export environment variables first. export YARN_CONF_DIR=${BIGDATA_HOME}/FusionInsight_HD_8.1.0.1/1_10_ResourceManager/etc
