yarn.resoucemanager.scheduler.address

yarn.resourcemanager.scheduler.address是YARN资源管理器调度器的地址。它用于指定资源管理器调度器的通信地址，以便其他组件和应用程序可以与调度器进行交互。这个地址通常是一个主机名和端口号的组合，例如"localhost:8030"。通过这个地址，应用程序可以向调度器提交作业请求，并获取有关资源分配和调度的信息。

Please check the values of 'yarn.scheduler.maximum-allocation-mb' and/or 'yarn.nodemanager.resource.memory-mb'.

The values of 'yarn.scheduler.maximum-allocation-mb' and 'yarn.nodemanager.resource.memory-mb' determine the maximum amount of memory that can be allocated to a single container running on a node in the YARN cluster.

'yarn.scheduler.maximum-allocation-mb' sets the maximum amount of memory that can be allocated to a single container by the YARN scheduler, while 'yarn.nodemanager.resource.memory-mb' sets the maximum amount of memory that can be allocated to a single container by the node manager.

To check the values of these parameters, you can use the following command:

yarn getconf -confKey yarn.scheduler.maximum-allocation-mb
yarn getconf -confKey yarn.nodemanager.resource.memory-mb

These commands will display the current values of these parameters in your YARN cluster.

解决 Please check the values of 'yarn.scheduler.maximum-allocation-mb' and/or 'yarn.nodemanager.resource.memory-mb'.

To solve the issue of checking the values of 'yarn.scheduler.maximum-allocation-mb' and/or 'yarn.nodemanager.resource.memory-mb' in a YARN cluster, you can follow these steps:

1. Open a terminal and SSH into the node where the YARN ResourceManager is running.

2. Run the following command to check the value of 'yarn.scheduler.maximum-allocation-mb':

yarn getconf -confKey yarn.scheduler.maximum-allocation-mb

This command will display the current value of 'yarn.scheduler.maximum-allocation-mb' in the YARN cluster.

3. Run the following command to check the value of 'yarn.nodemanager.resource.memory-mb':

yarn getconf -confKey yarn.nodemanager.resource.memory-mb

This command will display the current value of 'yarn.nodemanager.resource.memory-mb' in the YARN cluster.

4. If the values are not set to the desired values, you can set them using the following commands:

yarn config -set yarn.scheduler.maximum-allocation-mb <value>
yarn config -set yarn.nodemanager.resource.memory-mb <value>

Replace <value> with the desired value in megabytes (MB).

5. Restart the YARN ResourceManager and NodeManagers for the changes to take effect.

After following these steps, you should be able to check and set the values of 'yarn.scheduler.maximum-allocation-mb' and 'yarn.nodemanager.resource.memory-mb' in your YARN cluster.
