First I installed hadoop 2.6.0 on centos
(reference path, and configuration
http://www.rexamine.com/2015/02/installing-hadoop-2-6-0-on-centos-7/)
Installed hive and configure hive-default.xml
<name>javax.jdo.option.connectionURL</name>
<value>jdbc:derby:;databaseName=metastore_db:create=true</value>
-->> (changed)
<name>javax.jdo.option.connectionURL</name>
<value>jdbc:derby:;databaseName=/opt/hive(HIVE_HOME)metastore_db:create=true</value>
and I used data (https://github.com/reillywatson/nasdaq-outliers) nasdaq_daily_prices_*.csv file to create external table
(stock.hql)
create external table if not exists stocks(
...
location /user/hadoop/stock)
and I executed
hive -f stock.hql
and I executed too
bin/hive - e "describe extended stocks"
but hive return "table not found".
So how can I find external table and use it in hive and hadoop?
p.s My hadoop configuration is same in
http://www.rexamine.com/2015/02/installing-hadoop-2-6-0-on-centos-7/
and hive configuration is just changed
<value>jdbc:derby:;databaseName=/opt/hive(HIVE_HOME)metastore_db:create=true</value>
HADOOP_HOME=/opt/hadoop
HIVE_HOME=/opt/hive
