[jira] [Created] (HDFS-11805) Ensure LevelDB DBIterator is closed

Xiaoyu Yao created HDFS-11805:
---------------------------------

             Summary: Ensure LevelDB DBIterator is closed
                 Key: HDFS-11805
                 URL: https://issues.apache.org/jira/browse/HDFS-11805
             Project: Hadoop HDFS
          Issue Type: Sub-task
            Reporter: Xiaoyu Yao
            Assignee: Chen Liang
            Priority: Minor


DBIterator used in CblockManager/FilteredKeys/SQLCLI/OzoneMetadataManager should be closed after done with the iteration to avoid resource leaking. 

try-with-resource should fix that easily for most of the cases. FIlteredKeys may be a special case that I have not fully checked yet.
