             Summary: Make FSO and OBS bucket layouts independent of normalization config flag
                 Key: HDDS-5929
                 URL: https://issues.apache.org/jira/browse/HDDS-5929
             Project: Apache Ozone
          Issue Type: Sub-task
          Components: OM
            Reporter: Rakesh Radhakrishnan
            Assignee: Aryan Gupta


Presently FILE_SYSTEM_OPTIMIZED("FSO") and OBJECT_STORE("OBS") implementation depends on {{"ozone.om.enable.filesystem.paths"}} flag. This flag should be enabled explicitly for the FSO logic and disabled explicitly for the OBS logic. This task is to remove the dependency with the normalization config flag for the FSO and OBS bucket layouts. 

*case-1)* {{FSO bucket layout}} should normalize the given key path irrespective of the above flag value.

*case-2)* {{OBS bucket layout}} shouldn't normalize the given key path irrespective of the above flag value.

*case-3)* {{LEGACY bucket layout}} should read the configuration flag and perform normalize the given key path based on the above config flag.

+*Hint*+
// Set modification time and normalize key if required.
String keyName;
if (getBucketLayout() == BucketLayout.OBJECT_STORE) \{
  keyName = keyArgs.getKeyName(); // pure object store semantics.
} else if (getBucketLayout() == BucketLayout.FILE_SYSTEM_OPTIMIZED) \{
  keyName = validateAndNormalizeKey(true, keyArgs.getKeyName()); // pure FS semantics.
} else \{
  keyName = validateAndNormalizeKey(
      ozoneManager.getEnableFileSystemPaths(), keyArgs.getKeyName());
}
