Error information

Cause Analysis

There are no Kudu configurations on the actually running node (node where the worker instance is located).

Procedure

1. Add configuration file kudu.properties to all worker instance nodes in the Presto cluster.

   Path for storing the configuration file: /opt/Bigdata/MRS_xxx/1_x_Worker/etc/catalog/ (Change the path based on the actual cluster version.)

   Configuration file content:

   connector.name=kudu
   kudu.client.master-addresses=KuduMasterIP1:port,KuduMasterIP2:port,KuduMasterIP3:port  

   

   • Set the IP address and port number of the KuduMaster node based on the site requirements.
   • Add the file permission and owner group that are the same as those of other files in the file save path to the configuration file.

2. After the modification, choose Components > Kudu on the cluster details page, click More, and select Restart Service.
