Xiaoyu Yao commented on HDFS-12069:
-----------------------------------
Thanks [~cheersyang] for the update. Patch v8 looks good to me. Agree that we
can fix the cblock usage with a separate ticket.
3 more minor issues. +1 after that being fixed.
ContainerCache.java
Line 86: NIT: OzoneLevelDBStore should be changed to MetadataStore
OzoneMetadataManager.java
We should also change the LevelDBStore used by the localStorage Handler.
KeyUtils.java
Line 62: LevelDB handle should be MetadataStore handler.
