Downloading diagnostic bundles in Cloudera Data Warehouse on premises

You can download diagnostic bundles for troubleshooting a Virtual Warehouse in Cloudera Data Warehouse on premises. The diagnostic bundles contain log files for the sidecar containers that support Hive or Impala components and for the components themselves. These diagnostic bundles are stored on HDFS in the form of ZIP files.

The log files are generated when you run some workloads on your Virtual Warehouse.
