Kafka Pre-check

Checking the Source and Target Instance Versions

• Check whether the source and target instance versions meet the requirements. Currently, the Kafka instance version must be 3.x or 2.7. If the version is not in the matching list, a warning is generated.
  • Cause 1: The source Kafka instance version is not supported. Select a supported instance.

    Solution: Go to the Configure Source and Target page of the professional event stream job and select a source instance that meets the version requirements.

  • Cause 2: The target Kafka instance version is not supported. Select a supported instance.

    Solution: Go to the Configure Source and Target page of the professional event stream job and select a target instance that meets the version requirements.

• Check whether the source and target Kafka instances are of the same version. If not, a warning is generated.

  Cause: The source and target instances are of different versions. Check their versions.

  Solution: Check whether the source and target Kafka instance versions are the same in the Configure Source and Target page. If they are different, modify the source or target instance to ensure that they are the same. Otherwise, there may be compatibility and performance risks.

Checking the Source Connectivity

Check whether the VM where the event stream job is located can connect to the source Kafka instance.

• Cause 1: The source Kafka instance cannot be connected. Check whether the network configuration is correct.

  Solution:

  1. On the Kafka console, check whether the source instance is normal.
  2. Check whether the VPC and subnet of the event stream cluster can connect to the source Kafka instance.
• Cause 2: The source Kafka instance cannot be connected. Check whether the entered instance information is correct.

  Solution:

  1. On the Kafka console, check whether the source instance is normal.
  2. Check whether the VPC and subnet of the event stream cluster can connect to the source Kafka instance.
  3. Check whether the username and password of the source Kafka instance configured on the Configure Source and Target page are correct.

Checking the Target Connectivity

Check whether the VM where the event stream job is located can connect to the target Kafka instance.

• Cause 1: The target Kafka instance cannot be connected. Check whether the network configuration is correct.

  Solution:

  1. On the Kafka console, check whether the target instance is normal.
  2. Check whether the VPC and subnet of the event stream cluster can connect to the target Kafka instance.
• Cause 2: The target Kafka instance cannot be connected. Check whether the entered instance information is correct.

  Solution:

  1. On the Kafka console, check whether the target instance is normal.
  2. Check whether the VPC and subnet of the event stream cluster can connect to the target Kafka instance.
  3. Check whether the username and password of the target Kafka instance configured on the Configure Source and Target page are correct.

Checking the Source and Target Instance Specifications

Check whether the specifications of the source and target Kafka instances match.

Cause: The specifications of the source and target Kafka instances are inconsistent. Check the specifications of the source and target instances.

Solution: Check whether the specifications of the source and target Kafka instances are the same on the Configure Source and Target page. If not, modify the source or target instance to ensure that the specifications are the same.

Checking the Addresses of the Source and Target Instances

Check whether the source and target instance have the same IP address.

Cause: The source and target Kafka instances have the same IP address. Check the node IP addresses of the source and target instances.

Solution: Check the node connection addresses and IP addresses of the source and target instances. If they use the same IP address, modify either the source or target instance to ensure the IP addresses are unique.
