Examples with HadoopSerializationWrapper org.apache.ignite.internal.processors.hadoop.impl.v2.HadoopSerializationWrapper used on opensource projects

Example 1 with HadoopSerializationWrapper

use of org.apache.ignite.internal.processors.hadoop.impl.v2.HadoopSerializationWrapper in project ignite by apache.

the class HadoopSerializationWrapperSelfTest method testIntWritableSerialization.

/**
 * Tests read/write of IntWritable via native WritableSerialization.
 * @throws Exception If fails.
 */
public void testIntWritableSerialization() throws Exception {
    HadoopSerialization ser = new HadoopSerializationWrapper(new WritableSerialization(), IntWritable.class);
    ByteArrayOutputStream buf = new ByteArrayOutputStream();
    DataOutput out = new DataOutputStream(buf);
    ser.write(out, new IntWritable(3));
    ser.write(out, new IntWritable(-5));
    assertEquals("[0, 0, 0, 3, -1, -1, -1, -5]", Arrays.toString(buf.toByteArray()));
    DataInput in = new DataInputStream(new ByteArrayInputStream(buf.toByteArray()));
    assertEquals(3, ((IntWritable) ser.read(in, null)).get());
    assertEquals(-5, ((IntWritable) ser.read(in, null)).get());
}

Example 2 with HadoopSerializationWrapper

use of org.apache.ignite.internal.processors.hadoop.impl.v2.HadoopSerializationWrapper in project ignite by apache.

the class HadoopSerializationWrapperSelfTest method testIntJavaSerialization.

/**
 * Tests read/write of Integer via native JavaleSerialization.
 * @throws Exception If fails.
 */
public void testIntJavaSerialization() throws Exception {
    HadoopSerialization ser = new HadoopSerializationWrapper(new JavaSerialization(), Integer.class);
    ByteArrayOutputStream buf = new ByteArrayOutputStream();
    DataOutput out = new DataOutputStream(buf);
    ser.write(out, 3);
    ser.write(out, -5);
    ser.close();
    DataInput in = new DataInputStream(new ByteArrayInputStream(buf.toByteArray()));
    assertEquals(3, ((Integer) ser.read(in, null)).intValue());
    assertEquals(-5, ((Integer) ser.read(in, null)).intValue());
