Marcelo Vanzin commented on HIVE-8574:
--------------------------------------

Rounding up, each task metrics data structure will take around 256 bytes. So ~25MB?

> The current implementation of metrics gathering in the Spark client is a little hacky.
First, it's awkward to use (and the implementation is also pretty ugly). Second, it will just
collect metrics indefinitely, so in the long term it turns into a huge memory leak.
> We need a simplified interface and some mechanism for disposing of old metrics.
