---------------------------------------
Summary: Use proper capacity storage units such as KB, GB, TB
Key: IMPALA-11804
URL: https://issues.apache.org/jira/browse/IMPALA-11804
Project: IMPALA
Issue Type: Task
Components: Backend
Reporter: Abhishek Rawat
Most cloud vendors advertise storage in base 10 units such as 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, GiB, TiB) internally and
everywhere else such as web UI, query profile, etc.
The logic for parsing memory configs is here:
