Sqoop导出到SQL Server:模式？

Question

我想将HDFS中的数据导出到架构中的SQL Server表my_schema.

我试着--schema像导入命令:

sqoop export \
--libjars /opt/mapr/sqoop/sqoop-1.4.6/lib/sqljdbc4.jar \
--connect "jdbc:sqlserver://MY-SERVER-DNS;database=my_db;" \
--schema "myschema" \
--table "my_table" \
--export-dir /path/to/my/hdfs/dir

ERROR tool.BaseSqoopTool: Unrecognized argument: --schema

和 --table "schema.table"

sqoop export \
--libjars /opt/mapr/sqoop/sqoop-1.4.6/lib/sqljdbc4.jar \
--connect "jdbc:sqlserver://MY-SERVER-DNS;database=my_db;" \
--table "my_schema.my_table" \
--export-dir /path/to/my/hdfs/dir

INFO manager.SqlManager: 
Executing SQL statement: SELECT t.* FROM [my_schema.my_table] AS t WHERE 1=0 

ERROR manager.SqlManager: Error executing statement: 
com.microsoft.sqlserver.jdbc.SQLServerException:
Invalid object name 'my_schema.my_table'.

有没有办法用sqoop做到这一点？还是另一种技术？

编辑:

sqoop export \
--libjars /opt/mapr/sqoop/sqoop-1.4.6/lib/sqljdbc4.jar \
--connect "jdbc:sqlserver://MY-SERVER-DNS;database=my_db;schema=my_schema;" \
--table "my_table" \
--export-dir /path/to/my/hdfs/dir

INFO manager.SqlManager: Executing SQL statement: SELECT t.* FROM [my_table] AS t WHERE 1=0
16/07/25 10:46:21 ERROR manager.SqlManager: 
Error executing statement: com.microsoft.sqlserver.jdbc.SQLServerException:
Invalid object name 'my_table'.

这不是识别架构.

Answer 1

在连接字符串中提供架构:

jdbc:sqlserver://MY-SERVER-DNS;databaseName=my_db;schema=my_schema;

所以你的导出sqoop命令应该是:

sqoop export \
--libjars /opt/mapr/sqoop/sqoop-1.4.6/lib/sqljdbc4.jar \
--connect "jdbc:sqlserver://MY-SERVER-DNS;databaseName=my_db;schema=my_schema;" \
--table "my_table" \
--export-dir /path/to/my/hdfs/dir

也:

导入和导出作业都支持自定义模式 - 从sqoop指南中的语法,--schema应该传递为-- --schema:

所以你的导出sqoop命令应该是:

sqoop export \
--libjars /opt/mapr/sqoop/sqoop-1.4.6/lib/sqljdbc4.jar \
--connect "jdbc:sqlserver://MY-SERVER-DNS;databaseName=my_db;" \
--export-dir /path/to/my/hdfs/dir
--table "my_table" \
-- --schema my_schema \
