[jira] [Created] (HDFS-8330) BlockInfoContiguous in blocksMap can have null BlockCollection

Chengbing Liu created HDFS-8330:
-----------------------------------

             Summary: BlockInfoContiguous in blocksMap can have null BlockCollection
                 Key: HDFS-8330
                 URL: https://issues.apache.org/jira/browse/HDFS-8330
             Project: Hadoop HDFS
          Issue Type: Bug
          Components: namenode
    Affects Versions: 2.7.0
            Reporter: Chengbing Liu


In blocksMap, we have seen situations that some {{BlockInfoContiguous}} have its {{BlockCollection == null}}. This indicates orphan blocks which do not belong to any file.

See HDFS-8113 for more discussions.
