hive-05-Execution Error, return code 3 from org.apache.hadoop.hive.ql.exec.mr.MapredLocalTask

hive命令行里执行了一句话：

select * from person  join zhanghao   on person.zjhm = zhanghao.zjhm limit 100 ; 

就是两个表做连接查询，数据量大小一个是3千万，一个是3亿
结果报错

解决方法：
set hive.mapjoin.localtask.max.memory.usage=0.99
hive.mapjoin.localtask.max.memory.usage
•说明：本地任务可以使用内存的百分比 •默认值： 0.90，如果你的localtask mapjoin 表很小可以试试，但彻底解决需要
set hive.auto.convert.join=false;关闭自动mapjoin 但这个参数用的时候一定要注意，
如果你的sql 很长join会常多，关闭mapjoin任务数会成10倍激增，contener满了任务同样会非常之慢，set hive.auto.convert.join=false;一定要用在localtask级别这种超轻量及的job上。
