Question

我使用了一个select语句，比如'select T ** from xxx'来获取hive中表的hdfs目录位置。但现在我忘记了这个说法。有谁知道！谢谢！

所需的位置：

Location: file:/tmp/warehouse/part_table/d=abc

<强>样本

hive> DESCRIBE formatted part_table partition (d='abc');
OK
# col_name              data_type               comment            

i                       int                                        

# Partition Information         
# col_name              data_type               comment            

d                       string
