+
+<configuration>
+
+  <property>
+    <name>mapred.capacity-scheduler.queue.default.guaranteed-capacity</name>
+    <value>100</value>
+    <description>Percentage of the number of slots in the cluster that are
+      guaranteed to be available for jobs in this queue.
+    </description>    
+  </property>
+  
+  <property>
+    <name>mapred.capacity-scheduler.queue.default.reclaim-time-limit</name>
+    <value>300</value>
+    <description>The amount of time, in seconds, before which 
+      resources distributed to other queues will be reclaimed.
+    </description>
+  </property>
+
+  <property>
+    <name>mapred.capacity-scheduler.queue.default.supports-priority</name>
+    <value>false</value>
+    <description>If true, priorities of jobs will be taken into 
+      account in scheduling decisions.
+    </description>
+  </property>
+
+  <property>
+    <name>mapred.capacity-scheduler.queue.default.minimum-user-limit-percent</name>
+    <value>100</value>
+    <description> Each queue enforces a limit on the percentage of resources 
+    allocated to a user at any given time, if there is competition for them. 
+    This user limit can vary between a minimum and maximum value. The former
+    depends on the number of users who have submitted jobs, and the latter is
+    set to this property value. For example, suppose the value of this 
+    property is 25. If two users have submitted jobs to a queue, no single 
+    user can use more than 50% of the queue resources. If a third user submits
+    a job, no single user can use more than 33% of the queue resources. With 4 
+    or more users, no user can use more than 25% of the queue's resources. A 
+    value of 100 implies no user limits are imposed. 
+    </description>
+  </property>
+  <property>
+    <name>mapred.capacity-scheduler.queue.default.maximum-initialized-jobs-per-user</name>
+    <value>2</value>
+    <description>The maximum number of jobs to be pre-initialized for a user
+    of the job queue.

+  </property>
+  
+  
+  <property>
+    <name>mapred.capacity-scheduler.reclaimCapacity.interval</name>
+    <value>5</value>
+    <description>The time interval, in seconds, between which the scheduler
+     periodically determines whether capacity needs to be reclaimed for 
+     any queue.

+    <value>300</value>
+    <description>The amount of time, in seconds, before which 
+    resources distributed to other queues will be reclaimed by default
+    in a job queue.
+    </description>
+  </property>
+  
+  <property>
+    <name>mapred.capacity-scheduler.default-supports-priority</name>

+
+  <property>
+    <name>mapred.capacity-scheduler.task.default-pmem-percentage-in-vmem</name>
+    <value>-1</value>
+    <description>If mapred.task.maxpmem is set to -1, this configuration will
+      be used to calculate job's physical memory requirements as a percentage of
+      the job's virtual memory requirements set via mapred.task.maxvmem. This
+      property thus provides default value of physical memory for job's that
+      don't explicitly specify physical memory requirements.
+
+      If not explicitly set to a valid value, scheduler will not consider
+      physical memory for scheduling even if virtual memory based scheduling is
+      enabled(by setting valid values for both mapred.task.default.maxvmem and
+      mapred.task.limit.maxvmem).
+    </description>
+  </property>
+
+  <property>
+    <name>mapred.capacity-scheduler.task.limit.maxpmem</name>
+    <value>-1</value>
+    <description>Configuration that provides an upper limit on the maximum
+      physical memory that can be specified by a job. The job configuration
+      mapred.task.maxpmem should be less than this value. If not, the job will
+      be rejected by the scheduler.
+      
+      If it is set to -1, scheduler will not consider physical memory for
+      scheduling even if virtual memory based scheduling is enabled(by setting
+      valid values for both mapred.task.default.maxvmem and

+
+  <property>
+    <name>mapred.capacity-scheduler.default-maximum-initialized-jobs-per-user</name>

+    If number mentioned in property is equal to number of job queues
+    then a single thread would initialize jobs in a queue. If lesser
