Undoes dependency on MetaTableAccessor from hbase-balancer.
Moves MetaTableAccessor from hbase-balancer to hbase-server.
Adds a new hbase-tool module to host hbase tooling. In this
commit, we move favored nodes tooling here. In follow-on will
move other tooling here.
hbase-balancer/src/main/java/org/apache/hadoop/hbase/favored/FavoredNodeAssignmentHelper.java
hbase-server/src/main/java/org/apache/hadoop/hbase/favored/FavoredNodesManager.java
Moved the write-to-meta methods over to hbase-server into
FavoredNodeManager from FavoredNodesAssignmentHelper where they are needed.
Made the methods priivate.
hbase-server/src/main/java/org/apache/hadoop/hbase/master/SnapshotOfRegionAssignmentFromMeta.java
Moved this class back into hbase-server. It wants to scan meta
to calculate data structures already present in Master. Needs
rewrite to use Master if Favored Nodes feature is revived.
hbase-server/src/test/java/org/apache/hadoop/hbase/master/TestMasterOperationsForRegionReplicas.java
Bug fix. Was using wrong logger.
hbase-tool/src/main/java/org/apache/hadoop/hbase/tool/favored/AssignmentVerificationReport.java
hbase-tool/src/main/java/org/apache/hadoop/hbase/tool/favored/RegionPlacementMaintainer.java
Moved favored node tool and the reporter it uses here.
Updated class comments to explain it unused, needs work.
hbase-tool/src/test/java/org/apache/hadoop/hbase/tool/favored/TestRegionPlacement.java
Moved test for RegionPlacemenentMaintainer here.
