Cluster List

You can quickly view the status of all clusters and jobs by viewing the dashboard information, and obtain relevant MRS documents from Help in the left navigation pane on the MRS console.

MRS is used to manage and analyze massive data. It is easy to use. You can create a cluster and add MapReduce, Spark, and Hive jobs to the cluster to analyze and process user data. After being processed, you can transmit the data in SSL encryption mode to OBS to ensure data integrity and confidentiality.

Cluster Status

Log in to the MRS management console. You can view the status of existing clusters in the active cluster list. You search for status clusters in a specified status from the Status drop-down list. Table 1 lists all the cluster statuses.
Table 1 Cluster status

Status

Description

Starting

If a cluster is being created, the cluster is in the Starting state.

Running

If a cluster is successfully created and is running properly, its status is Running.

Scaling out

If the Master, Core, or Task node in a cluster is being added, the cluster is in the Scaling out state.

NOTE:

If the cluster scale-out fails, you can add node to the cluster again.

Scaling in

If a cluster node is being deleted, the cluster node is in the Scaling in state. This state shows when you scale in or elastically scale in a cluster node, decommission a node in a yearly/monthly cluster, change the OS, or reinstall the OS.

Abnormal

If some components in a cluster are abnormal, the cluster is Abnormal.

Deleting

If a pay-per-use cluster node is being deleted, the cluster status changes to Deleting. This state is displayed after you click Delete and confirm the deletion.

NOTE:

A yearly/monthly cluster cannot be deleted.

Frozen

If the grace period of a yearly/monthly resource expires but the resource is not renewed, or if the fee of a pay-per-use resource fails to be deducted and you have not topped up your account before the grace period expires, the system freezes the resource in the Frozen state.

NOTE:

A frozen cluster is unavailable and its all ECSs are shut down. After being unfrozen, the cluster returns to the Running state. If no renewal fee is paid, the cluster will be deleted after a specified period (called freeze period) and the cluster status will be changed to Deleted.

Restoring node...

If a faulty node in the cluster is being recovered, its status is Restoring node....

Job Status

Table 2 describes the status of jobs that you execute after logging in to the MRS management console.
