I using PIG to access a table batting_data created via HCatalog. While doing so I am facing an error saying the mentioned table was not not found. However this batting_data table is available in HIVE. I also understand that if the database name is not mentioned then default is assumed.
ERROR org.apache.pig.tools.grunt.Grunt - ERROR 1115: Table not found : default.batting_data table not found
I have setup hive-site.xml as below. Pls note am not using a remote server for the metastore but a local server which is mysql
<configuration> <property> <name>javax.jdo.option.ConnectionURL</name> <value>jdbc:mysql://localhost/metastore?createDatabaseIfNotExist=true</value> <description>the URL of the MySQL database</description> </property> <property> <name>javax.jdo.option.ConnectionDriverName</name> <value>com.mysql.jdbc.Driver</value> </property> <property> <name>javax.jdo.option.ConnectionUserName</name> <value>root</value> </property> <property> <name>javax.jdo.option.ConnectionPassword</name> <value>root</value> </property> <property> <name>hive.hwi.listen.host</name> <value>0.0.0.0</value> </property> <property> <name>hive.hwi.listen.port</name> <value>9999</value> </property> <property> <name>hive.hwi.war.file</name> <value>lib/hive-hwi-0.12.0.war</value> </property> <property> <name>hive.metastore.local</name> <value>true</value> </property>I have setup the below in my .bashrc for the PIG integration with HIVE and HCATALOG.
export PIG_OPTS=-Dhive.metastore.local=true export PIG_CLASSPATH=$HCAT_HOME/share/hcatalog/:$HIVE_HOME/lib/
The below statement will be loaded by default when the GRUNT shell when PIG starts.
REGISTER /home/shiva/hive-0.12.0/hcatalog/share/hcatalog/hcatalog-core-0.12.0.jar; REGISTER /home/shiva/hive-0.12.0/lib/hive-exec-0.12.0.jar; REGISTER /home/shiva/hive-0.12.0/lib/hive-metastore-0.12.0.jar;
The complete log of the error message is below. Any help in fixing this would be appreciated. Thanks.
