[jira] [Created] (HDFS-16647) Delete unused NameNode#FS_HDFS_IMPL_KEY

JiangHua Zhu created HDFS-16647:
-----------------------------------

             Summary: Delete unused NameNode#FS_HDFS_IMPL_KEY
                 Key: HDFS-16647
                 URL: https://issues.apache.org/jira/browse/HDFS-16647
             Project: Hadoop HDFS
          Issue Type: Improvement
          Components: namenode
    Affects Versions: 3.3.3
            Reporter: JiangHua Zhu


There's some history here, NameNode#FS_HDFS_IMPL_KEY was introduced in HDFS-15450, and something was removed later in HDFS-15533, but FS_HDFS_IMPL_KEY was kept.
Here are some discussion details:
https://github.com/apache/hadoop/pull/2229#discussion_r470935801

It seems to be cleaner to remove the unused NameNode#FS_HDFS_IMPL_KEY.
