Siddharth Wagle commented on HDDS-3133:
---------------------------------------
[~msingh] The org.apache.hadoop.hdfs.protocol.HdfsFileStatus#getFileId, is
defined in HdfsFileStatus, I looked at where this is called:
https://github.com/apache/hive/blob/1e15791987098a177625b16b468e96021fb6dd29/shims/0.23/src/main/java/org/apache/hadoop/hive/shims/Hadoop23Shims.java#L767
Ozone cannot implement HdfsFileStatus, so will this need Hive change also?
