             Summary: Sender and receiver side of exchange should operate 
within memory constraint
                 Key: IMPALA-6524
                 URL: https://issues.apache.org/jira/browse/IMPALA-6524
             Project: IMPALA
          Issue Type: Improvement
          Components: Distributed Exec
            Reporter: Tim Armstrong
            Assignee: Michael Ho


We should reserve memory for any required exchange buffers and allocate them 
from the buffer pool. This would ensure that queries won't allocate exchange 
buffers that will push them over the memory limit
