Hong Shen updated SPARK-16985:
------------------------------
    Description: 
In our cluster, sometimes the sql output maybe overrided. When I submit some 
sql, all insert into the same table, and the sql will cost less one minute, 
here is the detail,

1 sql1, 11:03 insert into table.
2 sql2, 11:04:11 insert into table.
3 sql3, 11:04:48 insert into table.
4 sql4, 11:05 insert into table.
5 sql5, 11:06 insert into table.
The sql3's output file will override the sql2's output file. here is the log:
{code}
