> Presently DatanodeManager uses constant  value -1 as [trackID|https://github.com/apache/hadoop/blob/HDFS-10285/hadoop-hdfs-project/hadoop-hdfs/src/main/java/org/apache/hadoop/hdfs/server/blockmanagement/DatanodeManager.java#L1607],
which is a temporary value. As per discussion with [~umamaheswararao], one proposal is to
use {{BlockCollectionId/InodeFileId}}.
