Ted Yu created HDFS-6902:
----------------------------

             Summary: FileWriter should be closed in finally block in 
BlockReceiver#receiveBlock()
                 Key: HDFS-6902
                 URL: https://issues.apache.org/jira/browse/HDFS-6902
             Project: Hadoop HDFS
          Issue Type: Bug
            Reporter: Ted Yu
            Priority: Minor


Here is code starting from line 828:
{code}
            try {
              FileWriter out = new FileWriter(restartMeta);
              // write out the current time.
              out.write(Long.toString(Time.now() + restartBudget));
              out.flush();
              out.close();
            } catch (IOException ioe) {
{code}
If write() or flush() call throws IOException, out wouldn't be closed.
