Subject Re: HiveContext is creating metastore warehouse locally instead of in hdfs
Date Fri, 01 Aug 2014 02:09:06 GMT
Hi, Yin and Andrew, thank you for your reply.
When I create table in hive cli, it works correctly and the table will be
found in hdfs. I forgot start hiveserver2 before and I started it today.
Then I run the command below:
    spark-shell --master spark://192.168.40.164:7077  --driver-class-path
conf/hive-site.xml
Furthermore, I added the following command:
    hiveContext.hql("SET
hive.metastore.warehouse.dir=hdfs://192.168.40.164:8020/user/hive/warehouse")
But then didn't work for me. I got the same exception as before and found
the table file in local directory instead of hdfs.
