我们正在使用Teradata TDCH 1.5 jar从Teradata提取数据并使用Sqoop导入Hive。
第一步，手动创建Hive表，并使用sqoop希望将数据加载到该表中。
Sqoop脚本：
#sqoop list-tables \
#--connection-manager org.apache.sqoop.teradata.TeradataConnManager \
#--connect $CONN --username $USER --password $PWD
sqoop import \
--connection-manager org.apache.sqoop.teradata.TeradataConnManager \
--connect $CONN --username $USER --password $PWD \
--table TESTSQOOP \
--hive-import \
--hive-table TESTSQOOP
