title: How to allocate specific number of mappers to multiple job in Hadoop?
body: <p>I am executing multiple PIG Scripts say script1, script2, script3, script4. In that I script1 is executing independently and script2,3,4 executing parallely after scripts get executed.
  I am giving input file of size 7-8 GB. So after executing script1, I am observing that instead of parallely executing script 2,3,4 only script2 is executing as it is consuming 33-35 mappers. Other remain in like queue (means script3,4 have not get mapper allocation). Due to this too much time requires to execute all scripts.</p>
  
  <p>So what I am thinking is that If I am able to set the limit of mapper to each script then may be time require to execute wll be less as all scripts may get allocation of mappers.</p>
  
  <p>So is there any way to allocate specific number of mappers to multiple scripts?</p>
