Chen Liang updated HDFS-11805:
------------------------------
Attachment: HDFS-11805-HDFS-7240.001.patch
Post v005 patch. {{SQLCLI}} is fixed in HDFS-11802. {{FilteredKeys}} has its
close method where the DBIterator gets closed, so does not seem to require a
fix.
> Ensure LevelDB DBIterator is closed

> 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.
