Have added your name to the contributor list and assigned the jira to you 
acknowledgement => acknowledgment  & cancelling =>canceling  seems to be not 
completely necessary, but any anyway patch seems to be fine and will commit it

> 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
