      Description

      The exception occurs during abandonFileInProgress().

      07/09/21 13:59:28 ERROR fs.FSNamesystem: java.lang.NullPointerException
              at org.apache.hadoop.dfs.FSNamesystem.internalReleaseCreate(FSNamesystem.java:1494)
              at org.apache.hadoop.dfs.FSNamesystem.access$100(FSNamesystem.java:50)
              at org.apache.hadoop.dfs.FSNamesystem$Lease.releaseLocks(FSNamesystem.java:1385)
              at org.apache.hadoop.dfs.FSNamesystem$LeaseMonitor.run(FSNamesystem.java:1447)
              at java.lang.Thread.run(Thread.java:595)
      

      My guess is that the client sends abandonFileInProgress() after create(), which timed out and was not executed by the name-node.
      That is why dir.getFileINode(src) returns null in internalReleaseCreate().
