sqoop操作出现问题

当我使用sqoop export命令将数据从配置单元导出到mirosoft sql server时，在ambary视图中使用sqoop actin和hcatalog时出现问题。
下面的命令在shell中正确运行，效果非常好。

sqoop export --connect 'jdbc:sqlserver://x.x.x.x:1433;useNTLMv2=true;databasename=BigDataDB'  --connection-manager org.apache.sqoop.manager.SQLServerManager --username 'DataApp' --password 'D@t@User' --table tr1 --hcatalog-database temporary --catalog-table 'daily_tr'

但是，当我在oozie工作流中使用此命令创建sqoop操作时，出现以下错误：

Failing Oozie Launcher, Main class [org.apache.oozie.action.hadoop.SqoopMain], main() threw exception, org/apache/hive/hcatalog/mapreduce/HCatOutputFormat

为解决此错误，我执行以下操作：
在workflow.xml所在的文件夹下，我创建文件夹lib并将sharedlibdir（/user/oozie/share/lib/lib_/hive）中的所有配置单元jar文件放在那里
我的目标是做到这一点，组件识别hcatalogjar文件和类路径，所以我不确定这一点，也许我不应该这样做，并为这个错误提供不同的解决方案
无论如何，执行此操作后，错误已更改如下：

我通过以下方法解决了我的问题：
1-在workflow.xml中的命令标记中使用（--hcatalog home/usr/hdp/current/hive webhcat）：

<?xml version="1.0" encoding="UTF-8" standalone="no"?>
<workflow-app xmlns="uri:oozie:workflow:0.5" name="loadtosql">
    <start to="sqoop_export"/>
    <action name="sqoop_export">
        <sqoop xmlns="uri:oozie:sqoop-action:0.4">
            <job-tracker>${resourceManager}</job-tracker>
            <name-node>${nameNode}</name-node>
            <command>export --connect jdbc:sqlserver://x.x.x.x:1433;useNTLMv2=true;databasename=BigDataDB --connection-manager org.apache.sqoop.manager.SQLServerManager --username DataApp--password D@t@User --table tr1 --hcatalog-home /usr/hdp/current/hive-webhcat --hcatalog-database temporary --hcatalog-table daily_tr </command>
            <file>/user/ambari-qa/test/lib/hive-site.xml</file>
            <file>/user/ambari-qa/test/lib/tez-site.xml</file>
        </sqoop>
        <ok to="end"/>
        <error to="kill"/>
    </action>
    <kill name="kill">
        <message>${wf:errorMessage(wf:lastErrorNode())}</message>
    </kill>
    <end name="end"/>
</workflow-app>

2-在hdfs上，在workflow.xml旁边创建lib文件夹，并将hive-site.xml和tez-site.xml放到其中（从/etc/hive/2.6.5.0-292/0/上传hive-site.xml，从/etc/tez/2.6.5.0-292/0/上传tez-site.xml到hdfs上的lib文件夹）
根据上面在工作流中定义的两个文件（hive-site.xml和tez-site.xml）

<file>/user/ambari-qa/test/lib/hive-site.xml</file>
<file>/user/ambari-qa/test/lib/tez-site.xml</file>

3-在job.properties文件中定义以下属性：

oozie.action.sharelib.for.sqoop=sqoop,hive,hcatalog

4-确保/etc/oozie/conf下的oozie-site.xml指定了以下属性。

<property> 
    <name>oozie.credentials.credentialclasses</name>
    <value>hcat=org.apache.oozie.action.hadoop.HCatCredentials</value>
</property>

我不知道这是不是罪魁祸首。一年前我在hdp中用sqoop1.4.x面对这个问题，它显示了一些无关的失败原因。
当您从命令行运行低于sqoop命令时，它将成功运行。

sqoop export --connect 'jdbc:sqlserver://x.x.x.x:1433;useNTLMv2=true;databasename=BigDataDB'  --connection-manager org.apache.sqoop.manager.SQLServerManager --username 'DataApp' --password 'D@t@User' --table tr1 --hcatalog-database temporary --catalog-table 'daily_tr'

但是当您通过ooziesqoop操作运行同一个命令时，它不应该像下面那样有单引号（'）。

<command>export --connect jdbc:sqlserver://x.x.x.x:1433;useNTLMv2=true;databasename=BigDataDB  --connection-manager org.apache.sqoop.manager.SQLServerManager --username DataApp --password D@t@User --table tr1 --hcatalog-database temporary --catalog-table daily_tr</command>
