MRS Flink Job¶
Functions¶
The MRS Flink node is used to execute predefined Flink jobs in MRS.
Parameters¶
Table 1 and Table 2 describe the parameters of the MRS Flink node.
Parameter | Mandatory | Description |
|---|---|---|
Node Name | Yes | Name of a node. The name must contain 1 to 128 characters, including only letters, numbers, underscores (_), hyphens (-), slashes (/), less-than signs (<), and greater-than signs (>). |
MRS Cluster Name | Yes | Select the MRS cluster. To create an MRS cluster, use either of the following methods:
|
Job Name | Yes | Name of an MRS job. The name contains 1 to 64 characters, including only letters, digits, and underscores (_). Note The job name cannot contain Chinese characters or more than 64 characters. If the job name does not meet requirements, the MRS job will fail to be submitted. |
Job Resource Package | Yes | Select a JAR package. Before selecting a JAR package, upload the JAR package to the OBS bucket, create a resource on the Manage Resource page, and add the JAR package to the resource management list. For details, see Creating a Resource. |
Job Execution Parameter | No | Key parameter of the program that executes the Flink job. This parameter is specified by a function in the user program. Multiple parameters are separated by space. |
Program Parameter | No | Used to configure optimization parameters such as threads, memory, and vCPUs for the job to optimize resource usage and improve job execution performance. Note This parameter is mandatory if the cluster version is MRS 1.8.7 or later than MRS 2.0.1. For details about the program parameters of MRS Flink jobs, see Managing an Existing Cluster > Job Management > Running a Flink Job in the MapReduce Service (MRS) User Guide. |
Input Data Path | No | Path where the input data resides. |
Output Data Path | No | Path where the output data resides. |
. On the Clusters page, create an MRS cluster.Parameter | Mandatory | Description |
|---|---|---|
Max. Node Execution Duration | Yes | Execution timeout interval for the node. If retry is configured and the execution is not complete within the timeout interval, the node will not be retried and is set to the failed state. |
Retry upon Failure | Yes | Indicates whether to re-execute a node task if its execution fails. Possible values:
Note If Timeout Interval is configured for the node, the node will not be executed again after the execution times out. Instead, the node is set to the failure state. |
Failure Policy | Yes | Operation that will be performed if the node task fails to be executed. Possible values:
