Changes ------- Addressed Jon's comments. Summary ------- Make it configurable to sideline some regions in big overlapped groups which hbck doesn't handle currently. The regions chose to sideline are those which overlap with most other regions. This addresses bug HBASE-5719. https://issues.apache.org/jira/browse/HBASE-5719 Diffs (updated) ----- src/main/java/org/apache/hadoop/hbase/util/HBaseFsck.java 54f9b21 src/main/java/org/apache/hadoop/hbase/util/RegionSplitCalculator.java 17678dd src/test/java/org/apache/hadoop/hbase/util/TestRegionSplitCalculator.java ac3b225 Diff: https://reviews.apache.org/r/4649/diff Testing ------- mvn -PlocalTests -Dtest=TestHBaseFsck* clean test Also tested in real system to fix inconsistencies.
