Question

背景： -

我正在使用HDP与spark1.6.0和hive 1.2.1

遵循的步骤： -

创建一个配置单元表： -

hive>
CREATE TABLE orctest(PROD_ID bigint, CUST_ID bigint, TIME_ID timestamp, CHANNEL_ID bigint, PROMO_ID bigint, QUANTITY_SOLD decimal(10,0), AMOUNT_SOLD decimal(10,0) ) CLUSTERED BY (PROD_ID) INTO 32 BUCKETS STORED AS ORC TBLPROPERTIES ( "orc.compress"="SNAPPY", "transactional"="true" );

将记录插入orctest

hive>
insert into orctest values(1, 1, '2016-08-02 21:36:54.000000000', 1, 1, 10, 10000);

尝试从spark-shell访问orctest表

scala>
val hiveContext = new org.apache.spark.sql.hive.HiveContext(sc)

val s = hiveContext.table("orctest")*

抛出异常： -

16/08/02 22:06:54 INFO OrcRelation: Listing hdfs://hadoop03:8020/apps/hive/warehouse/orctest on driver

任何帮助都将非常感激。

Answer 1

尝试设置：hiveContext.setConf("spark.sql.hive.convertMetastoreOrc", "false")

无法通过spark-sql
