      Description

      HDFS-7967 introduced a highly performant balancer getBlocks() query that scales to large/dense clusters. The simple design implementation depends on the triplets data structure. HDFS-9260 removed the triplets which fundamentally changes the implementation. Either that patch must be reverted or the getBlocks() patch needs reimplementation.
