Sqoop 无法列出查询中的列

Question

我从 sqoop 针对 mysql 数据库 (4.1.22-standard-log)

执行了这个简单的命令

sqoop import --connect jdbc:mysql://test.ddc:3306/test --table "foo" --username test --password bar --hive -table test.foo --as-avrodatafile --target-dir /user/admin/foo

我已将mysql-connector-java-5.1.31-bin.jar复制到/opt/cloudera/parcels/CDH-5.4.1-1.cdh5.4.1.p0.6/lib/sqoop/lib/

我遇到了这个错误

16/03/08 21:55:56 INFO manager.SqlManager: Executing SQL statement: SELECT t.* FROM `accessory` AS t LIMIT 1
16/03/08 21:55:56 ERROR manager.CatalogQueryManager: Failed to list columns from query: SELECT COLUMN_NAME FROM INFORMATION_SCHEMA.COLUMNS WHERE TABLE_SCHEMA = (SELECT SCHEMA())   AND TABLE_NAME = 'foo'

我能够解决这个问题。上面缺少驱动程序参数，这是导致问题的原因。下面的命令有效

sqoop import --connect jdbc:mysql://test.ddc:3306/test --table "foo" --driver 
com.mysql.jdbc.Driver --username test --password bar --hive-table test.foo --
as-avrodatafile --target-dir /user/admin/foo
