title: GC overhead limit exceeded container killed in Pig
body: <p>I am executing 13 table map join on our development environment in hadoop 2 cluster using YARN.All the table join as LEFT OUTER with main table .Total number of there 15 join join.</p>
  
  <p>Since most of the small table are less than 200-300 MBs,so I used USING 'replicated' to execute the script code.It executes quite fast but get stuck past 95-99% .When I check the application url ,2 reducers failed throwing error as "
  GC overhead limit exceeded container killed by the ApplicationMaster.Container killed on request.Exit code is 143 Container exited with a non-zero exit code 143".</p>
  
  <p>Other reducer failed with error Timed out after 300 secs Container killed by the ApplicationMaster.Container killed on request.Exit code is 143..</p>
