我正在尝试使用 ignite.sh 脚本启动服务器并收到上述错误（无法加载 HadoopV2Job）。"config/default-config.xml"正在传递给 CommandLineStartup 并且尚未更改。

有没有人遇到过这个问题或有人知道如何解决它？

我的 Ignite 版本是 1.4.0，这是完整的堆栈跟踪：

Shane，您是否使用 JDK8 编译了 Ignite 代码？看起来 org.objectweb.asm 库无法解析类“org.apache.ignite.internal.processors.hadoop.v2.HadoopV2Job”字节码，因为字节码版本高于 1.7：

/**
 * Constructs a new {@link ClassReader} object.
 * 
 * @param b
 *            the bytecode of the class to be read.
 * @param off
 *            the start offset of the class data.
 * @param len
 *            the length of the class data.
 */
public ClassReader(final byte[] b, final int off, final int len) {
    this.b = b;
    // checks the class version
    if (readShort(off + 6) > Opcodes.V1_7) {
        throw new IllegalArgumentException();
    }

请尝试使用 JDK 1.7 构建 Ignite 或使用 JDK8 指定目标级别 = 1.7。这能解决问题吗？
