原因：

MapJoinMemoryExhaustionHandler.java 中有如下代码

public void checkMemoryStatus(long tableContainerSize, long numRows)

  throws MapJoinMemoryExhaustionException {

    long usedMemory = memoryMXBean.getHeapMemoryUsage().getUsed();

    double percentage = (double) usedMemory / (double) maxHeapSize;

    String msg = Utilities.now() + "\tProcessing rows:\t" + numRows + "\tHashtable size:\t"

        + tableContainerSize + "\tMemory usage:\t" + usedMemory + "\tpercentage:\t" + percentageNumberFormat.format(percentage);

    console.printInfo(msg);

    if(percentage > maxMemoryUsage) {

      throw new MapJoinMemoryExhaustionException(msg);

    }

  }

最终解决办法：

hive在 0.11后 hive.auto.convert.join 自动为true，也就是如果满足条件会自动去做mapjoin， mapjoin的参数判断见
