Subject [jira] [Created] (HDFS-8546) Use try with resources in DataStorage and Storage
Date Fri, 05 Jun 2015 21:06:04 GMT
Andrew Wang created HDFS-8546:

             Summary: Use try with resources in DataStorage and Storage
                 Key: HDFS-8546
                 URL: https://issues.apache.org/jira/browse/HDFS-8546
             Project: Hadoop HDFS
          Issue Type: Improvement
          Components: datanode
    Affects Versions: 2.7.0
            Reporter: Andrew Wang
            Assignee: Andrew Wang
            Priority: Minor

We have some old-style try/finally to close files in DataStorage and Storage, let's update

Also a few small cleanups:
* Actually check that tryLock returns a FileLock in isPreUpgradableLayout
* Remove unused parameter from writeProperties
* Add braces for one-line if statements per coding style
