对一个小样本数据集（195行，22列）执行简单的查询要么抛出内存不足异常，要么遵循许多增加内存大小的建议，永不结束。
尝试的选项
设置hive.optimize.sort.dynamic.partition=true
增加tez记忆
增加内存和减少无序大小
增加记忆
更像那样
有时oom错误消失了，但它运行了几个小时却没有任何结果。。。
查询

select * lag(status, 1, null) over (partition by type_id order by time) as status_prev from sample_table

永不停止的查询示例

hive -hiveconf hive.tez.container.size=2048 -hiveconf hive.tez.java.opts=-Xmx1640m -hiveconf tez.runtime.io.sort.mb=820 -hiveconf tez.runtime.unordered.output.buffer.size-mb=205 -e "select * lag(status, 1, null) over (partition by type_id order by time) as status_prev from sample_table"

内存不足
