Question

我正在尝试使用sqoop导入具有CLOB数据类型的Oracle表数据，并且失败并显示错误Imported Failed: Cannot convert SQL type 2005。我正在使用Running Sqoop version: 1.4.5-cdh5.4.7。

请帮我介绍如何导入CLOB数据类型。

我使用以下oozie工作流程导入数据

<workflow-app xmlns="uri:oozie:workflow:0.4" name="EBIH_Dly_tldb_dly_load_wf">
        <credentials>
                <credential name="hive2_cred" type="hive2">
                        <property>
                                <name>hive2.jdbc.url</name>
                                <value>${hive2_jdbc_uri}</value>
                        </property>
                        <property>
                                <name>hive2.server.principal</name>
                                <value>${hive2_server_principal}</value>
                        </property>

最后，我在sqoop导入选项中使用了附加条款-D oraoop.disabled=true。

以下工作

<action name="sqp_imp_tldb_table1">
        <sqoop xmlns="uri:oozie:sqoop-action:0.2">
