### Description of PR When the name node is restarted with dfs.image.parallel.load enabled, the progress percentage(at namenode web) is reflacted after each thread finished after fsimage loading. For example, if dfs.image.parallel.target.sections=12(default), the percentage increases by 0% -> 8.3% (1/12) -> 16.6% (2/12) ->.... -> 100%. This is because each thread uses a separate counter. According docs of `org.apache.hadoop.hdfs.server.namenode.startupprogress.getCounter`, the counter guarantees thread-safe, so it seems that each fimage loading thread can use the same counter. ### How was this patch tested? run hadoop unit test and tested my test hadoop cluster (version 3.4.0) ### For code changes: - [x] Does the title or this PR starts with the corresponding JIRA issue id (e.g. 'HADOOP-17799.
