Subject [jira] Created: (HADOOP-1517) Three methods in FSNamesystem should not be synchronized.
Date Thu, 21 Jun 2007 19:40:25 GMT
Three methods in FSNamesystem should not be synchronized.
---------------------------------------------------------

                 Key: HADOOP-1517
                 URL: https://issues.apache.org/jira/browse/HADOOP-1517
             Project: Hadoop
          Issue Type: Bug
          Components: dfs
    Affects Versions: 0.13.0
            Reporter: Konstantin Shvachko
            Assignee: Konstantin Shvachko
            Priority: Critical
             Fix For: 0.14.0


Joining my UTF8 patch HADOOP-1283 with synchronization changes introduced by HADOOP-1269
I missed to remove synchronization modifiers in the following three methods:
startFile()
getAdditionalBlock()
allocateBlock()

Fine grained locking does not work if the first two methods are synchronized.
This is the patch that removes them.
