Subject [jira] Created: (HADOOP-3348) TestUrlStreamHandler hangs on LINUX
Date Tue, 06 May 2008 00:41:57 GMT
TestUrlStreamHandler hangs on LINUX
-----------------------------------

                 Key: HADOOP-3348
                 URL: https://issues.apache.org/jira/browse/HADOOP-3348
             Project: Hadoop Core
          Issue Type: Bug
          Components: fs
    Affects Versions: 0.18.0
         Environment: LINUX 2.6.9
            Reporter: lohit vijayarenu


TestUrlStreamHandler sets setURLStreamHandlerFactory as
{noformat)
FsUrlStreamHandlerFactory factory =
        new org.apache.hadoop.fs.FsUrlStreamHandlerFactory();
    java.net.URL.setURLStreamHandlerFactory(factory);
(noformat}

After this, MiniDFSCluster seems to hang while Datanodes tries to register in setNewStorageID,
specifically at
{noformat}
rand = SecureRandom.getInstance("SHA1PRNG").nextInt(Integer.MAX_VALUE);
{noformat}

jstack output shows that the main thread is stuck in RawLocalFileSystem$LocalFSFileInputStream.read

(Attaching the jstack)
