尝试在配置单元上运行查询时，出现以下错误：

FATAL [IPC Server handler 14 on 59490] org.apache.hadoop.mapred.TaskAttemptListenerImpl: Task: attempt_1457495991188_0166_m_000000_3 - exited : Java heap space

查询是：（变量$在执行前被替换）

FROM events_tmp 
INSERT INTO TABLE access PARTITION(day='$TODAY') 
SELECT $CFIELDS WHERE f0='access' AND f11 LIKE '$TODAY%' 
INSERT INTO TABLE access PARTITION(day='$YSTD') 
SELECT $CFIELDS WHERE f0='access' AND f11 LIKE '$YSTD%' 
INSERT INTO TABLE access PARTITION(day='$TMR') 
SELECT $CFIELDS WHERE f0='access' AND f11 LIKE '$TMR%' 
INSERT INTO TABLE downloads PARTITION(day='$TODAY') 
SELECT $IFIELDS WHERE f0='download' AND f36 LIKE '%dl%' AND f5 LIKE '$TODAY%'
INSERT INTO TABLE downloads PARTITION(day='$YSTD')
SELECT $IFIELDS WHERE f0='download' AND f36 LIKE '%dl%' AND f5 LIKE '$YSTD%'
INSERT INTO TABLE downloads PARTITION(day='$TMR') 
SELECT $IFIELDS WHERE f0='download' AND f36 LIKE '%dl%' AND f5 LIKE '$TMR%'

我在/usr/local/hive/conf/hive-env.sh中添加了export hadoop\u heapsize=4096，但它没有改变任何东西。。。。服务器上也有大量的空闲ram。
