farmmamba created HDFS-17126:
--------------------------------
Summary: FsDataSetImpl#checkAndUpdate should delete duplicated
block meta file.
Key: HDFS-17126
URL: https://issues.apache.org/jira/browse/HDFS-17126
Project: Hadoop HDFS
Issue Type: Improvement
Components: datanode
Affects Versions: 3.4.0
Reporter: farmmamba
Think about below case :
We have one datanode called dn1, it has two storages call ds1 and ds2
respectively.
Suppose we have blk_123 and blk_123_1001.meta in ds1 and blk_123_1001.meta in
ds2.
The current logic will not handle the file blk_123_1001.meta in ds2 and only
prints logs to tell us DirectoryScanner scan missing block files.
I think we should do something here.
