“无法分配内存”错误 - Java Runtime Environment的内存不足以继续。

Question

我一直在尝试使用hipi处理1000张图片 - 134MB，尝试网站Getting Started中给出的计算平均值教程。该程序适用于500张图像和100张图像。对于1000个图像，HIB创建速度很快，但我无法运行mapreduce。它说Java Runtime Environment没有足够的内存来继续。我的硬盘中有64 GB空间可供使用，我已将mapred-site.xml更新为 -

<property>
 <name>mapred.child.java.opts</name>
 <value>-Xmx8192m</value>
</property>

但是，我无法让它运行。
