Ke Han updated HDFS-16984: -------------------------- Description: h1. Symptoms The timestamp for a directory is lost after the upgrading from HDFS cluster 2.10.2 to 3.3.6. h1. Reproduce Start up a four-node HDFS cluster in 2.10.2 version. Execute the following commands. (The client is started up in NN, We have minimized the command sequence for reproducing) {code:java} bin/hdfs dfs -mkdir /GUBIkxOc bin/hdfs dfs -put -f -p -d /tmp/upfuzz/hdfs/GUBIkxOc/bQfxf /GUBIkxOc/ bin/hdfs dfs -mkdir /GUBIkxOc/sKbTRjvS{code} Perform read in the old version {code:java} bin/hdfs dfs -ls -t -r -u /GUBIkxOc/ Found 2 items drwxr-xr-x - root supergroup 0 1970-01-01 00:00 /GUBIkxOc/sKbTRjvS drwxr-xr-x - 20001 998 0 2023-04-17 16:15 /GUBIkxOc/bQfxf{code} Then perform a full-stop upgrade to upgrade the entire cluster to 3.3.6. (Follow upgrade procedure in the website). When all nodes have started up, we perform the same read {code:java} Found 2 items drwxr-xr-x - 20001 998 0 1970-01-01 00:00 /GUBIkxOc/bQfxf drwxr-xr-x - root supergroup 0 1970-01-01 00:00 /GUBIkxOc/sKbTRjvS {code} The timestamp info of directory /GUBIkxOc/bQfxf is lost. It changes from 2023-04-17 16:15 to 1970-01-01 00:00. I have also attached the required file: +/tmp/upfuzz/hdfs/GUBIkxOc/bQfxf+ . was: h1. Symptoms The timestamp for a directory is lost after the upgrading from HDFS cluster 2.10.2 to 3.3.5. h1. Reproduce Start up a four-node HDFS cluster in 2.10.2 version.
