How to assign a mapreduce process to a specific pool

[Raimon Bosch]

Hi all,

I'm trying to launch a process to map our log data into hive tables and I
was trying to assign this job to a specific pool name. This is our
configuration file:

--------- allocations.xml --------
<?xml version="1.0"?>
<allocations>

  <pool name="log2hive">
    <minMaps>14</minMaps>
    <minReduces>6</minReduces>
    <maxRunningJobs>1</maxRunningJobs>
    <minSharePreemptionTimeout>300</minSharePreemptionTimeout>
    <weight>1.0</weight>
  </pool>

  <defaultMinSharePreemptionTimeout>600</defaultMinSharePreemptionTimeout>
  <fairSharePreemptionTimeout>600</fairSharePreemptionTimeout>

</allocations>
--------- mapred-site.xml --------------
  <property>
    <name>mapred.jobtracker.taskScheduler</name>
    <value>org.apache.hadoop.mapred.FairScheduler</value>
  </property>

  <property>
    <name>mapred.fairscheduler.allocation.file</name>
    <value>/hadoop/conf/allocations.xml</value>
  </property>

My question is how can I use this new pool to launch jobs? I'm using `hadoop
jar` command but I would be also interested in assign pools from my code.


Thanks in advance,
