Data Analytics Studio
This topic describes the Data Analytics Studio (DAS) known issues for Cloudera Data Warehouse Private Cloud.
- DWX-9034: Query search page does not display the query history
- The default value of the pod PID limit setting on Openshift is 1024.
das-event-processorpod in the Data Catalog's namespace may run out of the available processes over time on OpenShift, causing the query search page to not display query history. You may also see the following exception in the Event Processor logs: "
ERROR com.hortonworks.hivestudio.eventProcessor.meta.MetaInfoUpdater - Error occurred while reading dump metadata null".
- You must manually restart the pod to resolve this issue. Alternatively, you can increase the pod PID limit or set it to maximum, which is a node level setting in Kubernetes/Openshift.
