-----------------------------------
Summary: Drill should support user/distribution specific
configuration checks during startup
Key: DRILL-6068
URL: https://issues.apache.org/jira/browse/DRILL-6068
Project: Apache Drill
Issue Type: New Feature
Affects Versions: 1.12.0
Reporter: Kunal Khatua
Assignee: Kunal Khatua
Fix For: 1.13.0
This is an evolution of the problem stated in DRILL-5741.
Currently, Drill does not leverage any information about the host machine
during start up and makes assumptions about the available resources (like
memory).
Further more, it is, often, up to the user to define the individual parameters
of memory for Drill: Heap, Direct and CodeCache.
The idea is to introduce a distribution and user specific configuration
checking scripts (distrib-auto.sh and drill-auto.sh) which follow the same
precedence as on the lines of distrib-env.sh and drill-env.sh.
A check for the existence of the `distrib-auto.sh` / `drill-auto.sh` scripts
will be performed and executed only if there is any executable lines of code.
Otherwise, the expected behaviour is that the startup functionality Drill will
continue as previous versions.
In combination with the requirement described for DRILL-5741; it would be nice
if a starting up Drillbit could be told upfront on the amount of memory it can
assume to access and automatically perform the allocations for the individual
parameters, while providing the ability for users to override (some or all of)
those settings.
