----------------------------------
Summary: Add command to purge data cache
Key: IMPALA-9189
URL: https://issues.apache.org/jira/browse/IMPALA-9189
Project: IMPALA
Issue Type: New Feature
Components: Backend
Affects Versions: Impala 3.3.0
Reporter: Michael Ho
It would be great to have a command to purge the data cache on demand so all
Impala compute nodes' data cache will be empty. This is useful for say
experimentation or demo purposes. cc'ing [~drorke], [~joemcdonnell]
