Rohini Palaniswamy created PIG-4922:
---------------------------------------

             Summary: Deadlock between SpillableMemoryManager and InternalSortedBag$SortedDataBagIterator
                 Key: PIG-4922
                 URL: https://issues.apache.org/jira/browse/PIG-4922
             Project: Pig
          Issue Type: Bug
            Reporter: Rohini Palaniswamy
            Assignee: Rohini Palaniswamy
             Fix For: 0.17.0, 0.16.1


  This one ran into a deadlock, when the data was really huge and InternalSortedBag was reading spilled data from disk.
{code}
grpd = FOREACH (GROUP data BY $0){
    sorted = ORDER data BY timestamp DESC;
    latest = LIMIT sorted 1;
    GENERATE latest;
};
{code}
