Method

ObjectserializeClone(final Object obj)
Creates a clone by serializing object and deserializing byte stream. 
ByteArrayOutputStream memOut = new ByteArrayOutputStream();
ObjectOutputStream objOut = new ObjectOutputStream(memOut);
objOut.writeObject(obj);
objOut.close();
ByteArrayInputStream src = new ByteArrayInputStream(memOut.toByteArray());
ObjectInputStream objIs = new ObjectInputStream(src);
return objIs.readObject();
voidserializeCookie(Object object, String filePath)
serialize Cookie 
OutputStream fos = null;
try {
    fos = new FileOutputStream(filePath);
    ObjectOutputStream oos = new ObjectOutputStream(fos);
    oos.writeObject(object);
    oos.flush();
    fos.close();
    oos.close();
...
ObjectserializedCopy(Object obj)
serialized Copy 
try {
    return deserialize(serialize(obj));
} catch (ClassNotFoundException e) {
    throw new RuntimeException("this shouldn't happen");
TserializedCopy(T object)
serialized Copy 
try {
    ByteArrayOutputStream baout = new ByteArrayOutputStream();
    ObjectOutputStream out = new ObjectOutputStream(baout);
    out.writeObject(object);
    out.flush();
    ObjectInputStream in = new ObjectInputStream(new ByteArrayInputStream(baout.toByteArray()));
    return (T) in.readObject();
} catch (Exception e) {
...
voidserializeDistributionType(String distributionType, String HadoopDistribution)
serialize Distribution Type 
FileWriter writer = new FileWriter(new File("./WEB-INF/classes/distributionInfo.properties"));
writer.write("DistributionType=" + distributionType);
writer.write("\n");
writer.write("HadoopDistribution=" + HadoopDistribution);
writer.close();
StringserializeExecutor(Object executor)
Serializes an Executor for execution with TaskModeAwareExecutorFactory 
if (executor instanceof Class) {
    Class c = (Class) executor;
    return "newinstance:" + c.getName();
} else {
    ByteArrayOutputStream oo = new ByteArrayOutputStream();
    ObjectOutputStream os = new ObjectOutputStream(oo);
    os.writeUnshared(executor);
    os.close();
...
ObjectserializeFromString(final String pString)
serialize From String 
try {
    final byte[] bytes = Base64.getDecoder().decode(pString);
    final ObjectInputStream ois = new ObjectInputStream(new ByteArrayInputStream(bytes));
    return ois.readObject();
} catch (final Exception pE) {
    throw new RuntimeException(pE);
byte[]serializeGZip(T obj)
serialize G Zip 
try {
    return serializeGZipSafe(obj);
} catch (Exception e) {
    throw new RuntimeException(e);
byte[]serializeInt(int i)
serialize Int 
ByteArrayOutputStream bos = new ByteArrayOutputStream(4);
DataOutputStream dos = new DataOutputStream(bos);
try {
    dos.writeInt(i);
} catch (IOException e) {
    throw new RuntimeException(e);
return bos.toByteArray();
...
byte[]serializeInt2MinLE(int value)
Returns the minimum bytes needed for the given value to encoded it in little-endian format. 
if (value < 0) {
    throw new IllegalArgumentException("Negative input value");
ByteArrayOutputStream byteStream = new ByteArrayOutputStream(4);
do {
    byteStream.write(value & 0xFF);
    value >>= 8;
} while (value != 0);
