apache-pig - 启动 PIG 时出错 : ERROR 2998: Unhandled internal error. 找到接口(interface) jline.Terminal，但需要类

Question

我从 apache 下载了 Pig，我已经安装了它，尝试使用 pig -x local 运行它

这是我得到的:

    15/12/10 15:06:26 INFO pig.ExecTypeProvider: Trying ExecType : LOCAL
15/12/10 15:06:26 INFO pig.ExecTypeProvider: Trying ExecType : MAPREDUCE

我的日志文件包含以下内容:

下载并解压包后，我执行了以下操作(pig 在/usr/local/pig 中):

export JAVA_HOME=/usr/lib/jvm/jdk1.7.0_79
  196  export PIG_PREFIX=/usr/local/pig
  197  export PATH=$PATH:$PIG_PREFIX/bin

有什么问题吗？

谢谢，塞尔维亚语
