Subject [jira] [Commented] (HDFS-11779) Ozone: KSM: add listBuckets
Date Wed, 31 May 2017 08:42:08 GMT

    [ https://issues.apache.org/jira/browse/HDFS-11779?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16030843#comment-16030843

Weiwei Yang commented on HDFS-11779:
------------------------------------

Thanks [~yuanbo] for the comments. I have fixed 2.a, 2.b in my v9 patch, additionally I added
an utility class {{LevelDBStore#StringKeyPrefixFilter}} for better re-use. Regarding to your
comment 1, thanks for pointing that out. It makes sense to me. Right now {{FilteredKeys}}
class lives in {{org.apache.hadoop.ozone.container.common.helpers}} which is not common for
all layers, I think we need another JIRA to refactor that code to call {{LevelDBStore#getRangeKVs}}
with {{LevelDBKeyFilter}}, [~anu] what do you think?
