版本： 2.3.0

準(zhǔn)備

保證spark的的各個(gè)節(jié)點(diǎn)上都有hive的包谎僻。

將hive的配置文件， hive-site.xml 拷貝到spark的 conf文件下 寓辱。

配置

在hive-site.xml中的參數(shù) hive.metastore.warehouse.dir 自版本 spark2.0.0 起廢棄了艘绍。 需要使用 spark.sql.warehouse.dir 來(lái)指定默認(rèn)的數(shù)據(jù)倉(cāng)庫(kù)目錄。 需要給該目錄提供讀寫(xiě)權(quán)限秫筏。

（但是實(shí)際來(lái)看诱鞠，hive.metastore.warehouse.dir 仍然在起作用，并且通過(guò)spark-sql創(chuàng)建的表也會(huì)在相應(yīng)的目錄下存在这敬。 ）
