Subject [jira] [Created] (HDFS-5884) LoadDelegator should use IOUtils.readFully() to read the magic header
Date Tue, 04 Feb 2014 22:28:09 GMT
Haohui Mai created HDFS-5884:
--------------------------------

             Summary: LoadDelegator should use IOUtils.readFully() to read the magic header
                 Key: HDFS-5884
                 URL: https://issues.apache.org/jira/browse/HDFS-5884
             Project: Hadoop HDFS
          Issue Type: Sub-task
            Reporter: Haohui Mai
            Assignee: Haohui Mai


Currently FSImageFormat.LoadDelegator reads the magic header using {FileInputStream.read()}.
It does not guarantee that the magic header is fully read. It should use IOUtils.readFully()
instead.
