             Summary: NN restart fails after RollingUpgrade from  3.1.3/3.2.1 to 3.3.0
                 Key: HDFS-15566
                 URL: https://issues.apache.org/jira/browse/HDFS-15566
             Project: Hadoop HDFS
          Issue Type: Bug
            Reporter: Brahma Reddy Battula


* After rollingUpgrade NN from 3.1.3/3.2.1 to 3.3.0, if the NN is restarted, it fails while replaying edit logs.
 * HDFS-14922, HDFS-14924, and HDFS-15054 introduced the *modification time* bits to the editLog transactions.

 * When NN is restarted and the edit logs are replayed, the NN reads the old layout version from the editLog file. When parsing the transactions, it assumes that the transactions are also from the previous layout and hence skips parsing the *modification time* bits.
 * This cascades into reading the wrong set of bits for other fields and leads to NN shutting down.
