我已经创建了50gb数据的 Impala Parquet表。我正在运行一个包含5个表的连接、数据分组和排序的查询。
在查询结束时，服务器没有响应任何输出数据，除非impala抛出任何异常。
在cloudera管理器上，我可以看到一个节点在几分钟后运行状况不佳。
查询：

select 
    d_year, s_city, p_brand1,
    sum(lo_revenue - lo_supplycost) as profit
from 
    lineorder_kylin_parqt_ext, dates_kylin_parqt_ext ,customer_kylin_parqt_ext, supplier_kylin_parqt_ext, part_kylin_parqt_ext
where 
    lo_custkey = c_custkey
    and lo_suppkey = s_suppkey
    and lo_partkey = p_partkey
    and lo_orderdate = d_datekey
    and c_region = 'AMERICA'
    and s_nation = 'UNITED STATES'
    and (d_year = 1997 or d_year = 1998)
    and p_category = 'MFGR#14'
group by 
    d_year, s_city, p_brand1
order by 
    d_year, s_city, p_brand1;
