Xiaoyu Yao commented on HDDS-250:
---------------------------------
Thanks [~hanishakoneru] for working on this. The patch v2 looks good to me.
Just few minor comments:
OzoneConsts.java
Line 74: comments need to be updated to reflect the
/volume/scmid/containerDirXXX/metadata (I see we have some related comments in
ContainerReader.java, may be add a reference here and remove the obsolete
comments)
Line 75: the comment can be removed to match the code change. Also suggest
document the metadata format on the DN side.
BlockDeletingService.java
Line 166: should we keep using the ContainerData base class here to make it
generic so that it can handle different containerdata subclasses? Based on
that, I like the original name for the ContainerData#getDataPath instead of
ContainerData#getChunksPath, which seems more tied to the KeyValueContainerData
implementation.
Line 170: can we add a check ensure the container is an instance of
KeyVlaueContainerData before cast? NIT: containerName ->container

> The following functions in ContainerData are redundant. MetadataPath and
> ChunksPath are specific to KeyValueContainerData.
> ContainerPath is the common path in ContainerData which points to the base
> dir of the container.
