Summary: LLAP: Usability issues with hive.llap.io.cache.orc.size
Key: HIVE-12220
URL: https://issues.apache.org/jira/browse/HIVE-12220
Project: Hive
Issue Type: Bug
Components: Hive
Affects Versions: llap
Reporter: Carter Shanklin
In the llap-daemon site you need to set, among other things,
llap.daemon.memory.per.instance.mb
and
hive.llap.io.cache.orc.size
The use of hive.llap.io.cache.orc.size caused me some unnecessary problems,
initially I entered the value in MB rather than in bytes. Operator error you
could say but I look at this as a fraction of the other value which is in mb.
Second, is this really tied to ORC? E.g. when we have the vectorized text
reader will this data be cached as well? Or might it be in the future?
I would like to propose instead using hive.llap.io.cache.size.mb for this
setting.
