Hi Started Name Node and Data Node by configuring multiple DataDirs Written one file copied same block to another dataDir
What I expect is,Block will be removed from copied Dir since it's not present memory. But here it's keep on logging following for every directory scan ...Please let me know the behavior... 2012-06-18 16:30:55,152 WARN org.apache.hadoop.hdfs.server.datanode.fsdataset.impl.FsDatasetImpl: Block file /opt/dfs12/current/BP-1134724852-*********-1339770849071/current/finalized/blk_92866283154406728 does not match file found by scan /opt/dfs12/current/BP-1134724852-*********-1339770849071/current/finalized/subdir9/blk_92866283154406728 2012-06-18 16:35:55,152 INFO org.apache.hadoop.hdfs.server.datanode.DirectoryScanner: BlockPool BP-1134724852-*********-1339770849071 Total blocks: 389, missing metadata files:0, missing block files:0, missing blocks in memory:1, mismatched blocks:0 2012-06-18 16:35:55,152 WARN org.apache.hadoop.hdfs.server.datanode.fsdataset.impl.FsDatasetImpl: Block file /opt/dfs12/current/BP-1134724852-*********-1339770849071/current/finalized/blk_92866283154406728 does not match file found by scan /opt/dfs12/current/BP-1134724852-*********-1339770849071/current/finalized/subdir9/blk_92866283154406728
