如何在Spark SQL中創建數據庫

Question

如何在sparkSQL中創建數據庫或多個數據庫。我正在從spark-sql CLI執行SQL。像蜂巢create database sample_db這樣的查詢在這裏不起作用。我的系統上安裝了Hadoop 2.7和Spark 1.6。

Answer 1

spark.sql("create database test") 

//fetch metadata data from the catalog. your database name will be listed here 
spark.catalog.listDatabases.show(false) 

Answer 2

CREATE (DATABASE|SCHEMA) [IF NOT EXISTS] db_name
[COMMENT comment_text]
[LOCATION path]
[WITH DBPROPERTIES (key1=val1, key2=val2, ...)]
