Subject [jira] [Created] (HDFS-10620) StringBuilder created and appended even if logging is disabled
Date Wed, 13 Jul 2016 21:00:23 GMT
Staffan Friberg created HDFS-10620:
--------------------------------------

             Summary: StringBuilder created and appended even if logging is disabled
                 Key: HDFS-10620
                 URL: https://issues.apache.org/jira/browse/HDFS-10620
             Project: Hadoop HDFS
          Issue Type: Bug
          Components: namenode
    Affects Versions: 2.6.4
            Reporter: Staffan Friberg


In BlockManager.addToInvalidates the StringBuilder is appended to during the delete even if
logging isn't active.

Could avoid allocating the StringBuilder as well, but not sure if it is really worth it to
add null handling in the code.
