[jira] [Commented] (HIVE-13653) improve config error messages for LLAP cache size/etc

["Prasanth Jayachandran (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/HIVE-13653?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15267383#comment-15267383 ] 

Prasanth Jayachandran commented on HIVE-13653:
----------------------------------------------

nit: MIN_SIZE. minimum of what? arena or io memory? rename accordingly.
nit: '(not recommended)' in exception msg. can we not suggest if we don't recommend it? Options confuse users :)

Otherwise, +1

Orthogonal issue, can we make all these sizes derivable from 1 config? For example: If IO is enabled, derive the size from -Xmx in 'auto' mode. 10% Xmx = IO memory.  10% IO memory = min allocation, 40% IO memory = max allocation, Min(1GB, 25% IO memory) = Arena size etc.
