-------------------------------------
Summary: PlannerTests should assign HBase splits as part of the
test
Key: IMPALA-7061
URL: https://issues.apache.org/jira/browse/IMPALA-7061
Project: IMPALA
Issue Type: Bug
Components: Frontend, Infrastructure
Affects Versions: Impala 2.13.0, Impala 3.1.0
Reporter: Joe McDonnell
Assignee: Joe McDonnell
Some frontend PlannerTests rely on HBase tables being split into specific
regions with those regions assigned to specific region servers. Right now, the
HBase tables are created via the HBase shell with a single region, then they
are populated via Hive DMLs, then there is a Java program that splits the
tables into appropriate regions and assigns those regions to region servers.
Once that is done, nothing is maintaining the assignments. The Java code for
doing the splitting is hard to maintain and flaky. The assignments can
sometimes drift due to rebalancing.
We should convert this to specify the splits at HBase table creation time. We
should have the frontend PlannerTest do assignments at setup time to avoid
flakiness due to rebalancing. This should move some flakiness out of dataload.
