From 1633d9d61dddfcf8c70ab2f3b8e4dca94b9f2f1a Mon Sep 17 00:00:00 2001 From: Michael Stack Date: Sat, 21 Apr 2018 08:37:25 -0700 Subject: [PATCH] HBASE-20470 [2.0.0RC1] has broken unit tests... Fix test that depended upon flush being slow and one family only. Fix MemStoreSize compare to allow passing alternate implementation (needed when IMC was no longer default everywhere). --- .../apache/hadoop/hbase/coprocessor/RegionObserver.java | 3 --- .../org/apache/hadoop/hbase/regionserver/MemStoreSize.java | 5 ++++- .../hbase/regionserver/TestPerColumnFamilyFlush.java | 7 +++++-- 3 files changed, 9 insertions(+), 6 deletions(-) diff --git a/hbase-server/src/main/java/org/apache/hadoop/hbase/coprocessor/RegionObserver.java b/hbase-server/src/main/java/org/apache/hadoop/hbase/coprocessor/RegionObserver.java index 7391f6f21e7..c14cbd162f5 100644 --- a/hbase-server/src/main/java/org/apache/hadoop/hbase/coprocessor/RegionObserver.java +++ b/hbase-server/src/main/java/org/apache/hadoop/hbase/coprocessor/RegionObserver.java @@ -19,8 +19,6 @@ package org.apache.hadoop.hbase.coprocessor; -import edu.umd.cs.findbugs.annotations.NonNull; - import java.io.IOException; import java.util.List; import java.util.Map; @@ -199,7 +197,6 @@ public interface RegionObserver { * @param scanner the scanner over existing data used in the memstore segments being compact * @return the scanner to use during in memory compaction.
