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:

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。
