I'm trying to understand a little more about what these options do behind the scenes when pressed? I found this post, but it never got any responses (http://community.cloudera.com/t5/Web-UI-Hue-Beeswax/What-is-under-the-hood-of-Hue-Impala-editor-Clea...)
This is the one I am not too sure what happens
Perform Incremental metadata Update
I assume this issues a refresh command for all tables within the current database which is been viewed? If no database is veiwed does it do it for everything?
Invalidate All metadata and rebuild index
Same as above, but rather than refresh it invalidates full metadata? If no database is veiwed does it do it for everything?
