--------------------------------------------
Summary: Sync between dev-support/hbase_eclipse_formatter.xml and
hbase/checkstyle.xml
Key: HBASE-20837
URL: https://issues.apache.org/jira/browse/HBASE-20837
Project: HBase
Issue Type: Task
Affects Versions: 1.4.5, 2.0.1, 3.0.0
Reporter: Tak Lon (Stephen) Wu
While working on HBASE-20557 contribution, we figured out that the checkstyle
build target (ImportOrder's `groups`
[http://checkstyle.sourceforge.net/config_imports.html] ) was different from
the development supported IDE formatter, we would provide a fix here to sync
between dev-support/hbase_eclipse_formatter.xml and hbase/checkstyle.xml
This might need to backport the changes of master to branch-1 and branch-2 as
well.
Before this change, this is what checkstyle is expecting
