环境为hadoop2.2，在linux下运行自己的job，报如下错误：

Exception from container-launch: ExitCodeException exitCode=1: 
ExitCodeException exitCode=1:

Container exited with a non-zero exit code 1

但运行自带wordcount却能正常执行。google了很久，无非都是建议在mapred-site.xml中增加：

<property>
       <name>mapreduce.application.classpath</name>
       <value>
            /usr/local/cluster/hadoop-2.2.0/etc/hadoop,
            /usr/local/cluster/hadoop-2.2.0/share/hadoop/common/*,
            /usr/local/cluster/hadoop-2.2.0/share/hadoop/common/lib/*,
            /usr/local/cluster/hadoop-2.2.0/share/hadoop/hdfs/*,
            /usr/local/cluster/hadoop-2.2.0/share/hadoop/hdfs/lib/*,
            /usr/local/cluster/hadoop-2.2.0/share/hadoop/mapreduce/*,
            /usr/local/cluster/hadoop-2.2.0/share/hadoop/mapreduce/lib/*,
            /usr/local/cluster/hadoop-2.2.0/share/hadoop/yarn/*,
            /usr/local/cluster/hadoop-2.2.0/share/hadoop/yarn/lib/*
       </value>
</property>

但是问题依旧。从log中发现一个奇怪的输出：

Improperly specified VM option 'PretenureSizeThreshold'
Error: Could not create the Java Virtual Machine.
Error: A fatal exception has occurred. Program will exit.

立刻想到自己设置的mapred.child.java.opts参数，其中就有PretenureSizeThreshold，原来是不支持这个参数导致。修改后就能正确运行，居然折腾了很久。
