      Description

      I occasionally find the following warning in CDH clusters, but haven't figured out why. Thought I should better raise the issue anyway.

      2018-05-29 09:15:58,092 WARN org.apache.hadoop.hdfs.server.datanode.DataNode: Can't replicate block BP-725378529-10.0.0.8-1410027444173:blk_13276745777_1112363330268 because on-disk length 175085 is shorter than NameNode recorded length 9223372036854775807

      Infact, 9223372036854775807 = Long.MAX_VALUE.

      Chasing in the HDFS codebase but didn't find where this length could come from
