Troubleshooting Spark Deployment

If you encounter any issues when you deploy Spark on Relate 360, use the following information to troubleshoot the issues.

The ingestion of streaming data failed with too many ZooKeeper connections error.

When an ingestion request uses multithreaded processing and exceeds the allowed number of concurrent ZooKeeper connections, the ingestion of streaming data fails with the following error message:

Too many connections from <Client> - max is 60

Default is 60 connections. To fix this issue, increase the allowed number of concurrent ZooKeeper connections. To configure the allowed number of concurrent ZooKeeper connections, use the

maxClientCnxns

property in the ZooKeeper configuration file.
