如果您无法设置Iceberg表的自定义位置,那么默认情况下,Iceberg表将在HDFS上的默认位置存储。
默认位置为:`hdfs://<namenode>:<port>/warehouse/<database>.db/<table_name>`。
您可以通过以下方式设置默认位置:
1. 在创建表时指定位置:
```python
from pyspark.sql import SparkSession
from pyspark.sql.functions import *
spark = SparkSession.builder.appName("IcebergTable").getOrCreate()
spark.sql("""
CREATE TABLE db_name.table_name
USING iceberg
LOCATION 'hdfs://<namenode>:<port>/warehouse/db_name.db/table_name'
""")
```
2. 在Iceberg表的配置中指定位置:
```python
from pyspark.sql import SparkSession
from pyspark.sql.functions import *
spark = SparkSession.builder.appName("IcebergTable").getOrCreate()
spark.conf.set("spark.sql.catalog.db_name.table_name.location",
"hdfs://<namenode>:<port>/warehouse/db_name.db/table_name")
spark.sql("""
CREATE TABLE db_name.table_name
USING iceberg
""")
```
请注意,如果您更改了默认位置,则在使用表时需要指定新位置。例如:
```python
from pyspark.sql import SparkSession
from pyspark.sql.functions import *
spark = SparkSession.builder.appName("IcebergTable").getOrCreate()
spark.conf.set("spark.sql.catalog.db_name.table_name.location",
"hdfs://<namenode>:<port>/warehouse/new_location")
df = spark.read.format("iceberg").load("db_name.table_name")
```
