Subject [jira] Created: (HDFS-920) Incorrect metrics reporting of transcations metrics.
Date Tue, 26 Jan 2010 00:28:35 GMT
Incorrect metrics reporting of transcations metrics.  
------------------------------------------------------

                 Key: HDFS-920
                 URL: https://issues.apache.org/jira/browse/HDFS-920
             Project: Hadoop HDFS
          Issue Type: Bug
          Components: name-node
    Affects Versions: 0.20.1, 0.20.2, 0.21.0, 0.22.0
            Reporter: Ravi Phulari
             Fix For: 0.20.2


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 twelve block write + 1 for close file ) which is reported incorrectly
as 3.
