Changes ------- Updated it per Ted's comment. Summary ------- Some HRegionInfo related comparator doesn't consider empty end key. That's why there are some hacks in HRegionInfo's containsRange and containsRow method to check empty key. However, due to this issue, SplitParentFirstComparator has a bug. This addresses bug HBASE-4927. https://issues.apache.org/jira/browse/HBASE-4927 Diffs (updated) ----- src/main/java/org/apache/hadoop/hbase/HRegionInfo.java 2a24d0b src/main/java/org/apache/hadoop/hbase/master/CatalogJanitor.java b356b22 src/test/java/org/apache/hadoop/hbase/master/TestCatalogJanitor.java e047e30 src/test/java/org/apache/hadoop/hbase/regionserver/TestHRegionInfo.java baca241 Diff: https://reviews.apache.org/r/2992/diff Testing ------- TestHRegionInfo and TestCatalogJanitor are geen.
