Hi, 
I am using hadoop 2.2, and don't know how to set max input split size I would like to decrease this value, in order to create more mappers I tried updating yarn-site.xml, and but it does not work

indeed, hadoop 2.2 /yarn does not take of none the following settings

<property>
<name>mapreduce.input.fileinputformat.split.minsize</name>
<value>1</value>
</property>
<property>
<name>mapreduce.input.fileinputformat.split.maxsize</name>
<value>16777216</value>
</property>

<property>
<name>mapred.min.split.size</name>
<value>1</value>
</property>
<property>
<name>mapred.max.split.size</name>
<value>16777216</value>
</property>
best,
