Xiaoyu Yao commented on HDFS-11775:
-----------------------------------
Thanks @Nandakuma for working on this. The patch looks good to me overall. Here
are a few comments:
BucketManager.java
Since most of existing KSM/SCM don't have a separate interface in the package
name,
let's keep them together for consistency.
Line 26: need javac doc for the public methods.
DistributedStorageHandler.java
Line 71: unused import
import static org.apache.hadoop.scm.storage.ContainerProtocolCalls.putKey;
KsmBucketArgs.java
Line 102/110: extra space between public and List
KeySpaceManagerProtocol.proto
Line 161/176: Can we rename this to isVersionEnabled and use simple boolean
instead?
If yes, we should make this optional with default=false.
Line 166: we should use the StorageTypeProto defined in hdfs.proto instead of
define a new one StorageType.
Line 181: NIT: suggest rename OzoneACLType to OzoneAclType for consistency.
Line 186: NIT: suggest rename OzoneACLRights to OzoneAclRights for consistency.
KSMException.java/OzoneAcl.java
We might need some Acl related error codes later. It is OK for now since the
AclCheck
is not implemented yet in OzoneAcl.java. Please open a separate ticket if we
don't have one for that yet.
TestBucketManagerImpl.java
Line 122: you can use thrown.expectMessage to validate the expected exception.
