bharath v commented on IMPALA-6877:
-----------------------------------

bq. The most we can do is keep a track externally of which patterns have been 
added and have an option in the debug page to reset them to the global "-v" 
level. But then we will have to do that everytime we change the "-v" level.

IMO, that is a reasonable feature to have. But, why do we need to do that every 
time -v changes? Isn't that polled directly from FLAGS_v?

> Allow setting -vmodule from debug page
