How to transfer mysql table to hive?

I have a large mysql table that I would like to transfer to a Hadoop/Hive table. Are there st开发者_Go百科andard commands or techniques to transfer a simple (but large) table from Mysql to Hive? The table stores mostly analytics data.

1. First of all download mysql-connector-java-5.0.8 and put the jar to lib and bin folder of Sqoop

2. Create the table definition in Hive with exact field names and types as in mysql

   sqoop import --verbose --fields-terminated-by ',' --connect jdbc:mysql://localhost/test --table employee --hive-import --warehouse-dir /user/hive/warehouse --fields-terminated-by ',' --split-by id --hive-table employee

test - Database name

employee - Table name (present in test)

/user/hive/warehouse - Directory in HDFS where the data has to be imported

--split-by id - id can be the primary key of the table 'employee'

--hive-table employee - employee table whose definition is present in Hive
