> Most cloud vendors advertise storage in base 10 units such as KB, MB, GB, TB. Impala considers these storage units to be base 2. This could cause issue because when configuring data_cache or scratch_space Impala could try to use more capacity than what the underlying storage provides.
> It's okay for Impala to use base 2 units, but it should support configs using base 10 units and also use proper units (KiB, MiB, GiB, TiB) internally and everywhere else such as web UI, query profile, etc.
> The logic for parsing memory configs is here: [https://github.com/apache/impala/blob/master/be/src/util/parse-util.cc#L39]
