> Transaction metrics *transactions.getPreviousIntervalNumOps()* reported for name node edit logs are reporting incorrect metrics. 
> Transaction metrics should report 3 transactions upon creating a file of 1 block size - ( 1 for create file + 1 for one block write + 1 for close file ) which is reported correctly.
> Similarly metrics should report 12 transactions upon creating a file of 10 block size - ( 1 for create file + 10 for ten block writes + 1 for close file ) which is reported incorrectly as 3.
