      Description

      I am conducting research on log related bugs. I tried to make a tool to fix repetitive yet simple patterns of bugs that are related to logs. Typos in log messages are one of the reoccurring bugs. Therefore, I made a tool find typos in log statements. During my experiments, I managed to find the following typos in Hadoop MapReduce:

      In file /hadoop-mapreduce-project/hadoop-mapreduce-client/hadoop-mapreduce-client-app/src/main/java/org/apache/hadoop/mapred/TaskAttemptListenerImpl.java, LOG.info("Done acknowledgement from " + taskAttemptID.toString()),
      acknowledgement should be acknowledgment

      In file /hadoop-mapreduce-project/hadoop-mapreduce-client/hadoop-mapreduce-client-app/src/main/java/org/apache/hadoop/mapreduce/jobhistory/JobHistoryEventHandler.java, LOG.info("Exception while cancelling delayed flush timer. "+ "Likely caused by a failed flush " + e.getMessage()),
      cancelling should be canceling

      In file /hadoop-mapreduce-project/hadoop-mapreduce-client/hadoop-mapreduce-client-core/src/main/java/org/apache/hadoop/mapred/Task.java, LOG.info("Runnning cleanup for the task"),
      Runnning should be Running

      In file /hadoop-mapreduce-project/hadoop-mapreduce-client/hadoop-mapreduce-client-shuffle/src/main/java/org/apache/hadoop/mapred/ShuffleHandler.java, LOG.info("Storing state DB schedma version info " + getCurrentVersion()),
      schedma should be schema
