Brahma Reddy Battula updated HDFS-10810: ---------------------------------------- Description: 1)Batch IBR is enabled with number of committed blocks allowed=1 2) Written one block and closed the file without waiting for IBR 3)Setreplication called immediately on the file. So till the finalized IBR Received, block will not be added to {{neededReconstruction}} since following check will be {{false}} as block is not marked as complete. {code} if (isNeededReconstruction(block, repl.liveReplicas())) { neededReconstruction.update(block, repl.liveReplicas(), repl.readOnlyReplicas(), repl.decommissionedAndDecommissioning(), curExpectedReplicas, curReplicasDelta, expectedReplicasDelta); }.{code} Hence block will not marked as under-replicated. was: 1)Batch IBR is enabled with number of committed blocks allowed=1 2) Written one block and closed the file without waiting for IBR 3)Setreplication called immediately on the file.
