The flag --query_log_size controls the number of query profiles that are
retained. By default it's 25. There is no time-based retention policy for
profiles.

Lifetime of query details in the impalad web server

[Thoralf Gutierrez]

Hello everybody,

We think the impalad web server has invaluable information for our users to
analyze their queries as they are being executed, such as the query plan on
pages like
http://impala:25000/query_plan?query_id=e5421fea0f478563:3cffcc52

Unfortunately, these pages seem to be very ephemeral for us. After a couple
of minutes, trying to visit that page returns the error "Error: Unknown
query id: e5421fea0f478563:3cffcc52"

Does someone know of a way to increase the lifetime of these pages?

Thanks for your help,
Thoralf
