在oozie工作流程中使用hcatalog进行sqoop操作有问题

当我使用sqoop export命令将数据从蜂巢导出到mirosoft sql server时，在ambary-views中将sqoop actin与hcatalog一起使用时遇到问题。

以下命令在shell中正确运行，效果很好。

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工作流程中使用此命令创建sqoop操作时，出现以下错误：

要解决此错误，请执行以下操作：

  • 在workflow.xml所在的文件夹下，我创建文件夹lib，并将所有来自sharedlibDir（/ user / oozie / share / lib / lib_lib_201806281525405 / hive的hive jar文件放在其中。

我的目标是这样做，组件可以识别hcatalog jar文件和类路径，因此我不确定，也许我不应该这样做，并针对此错误采取不同的解决方案

无论如何，该错误已更改如下：

版本：

HDP 2.6.5.0

纱线2.7.3

配置单元1.2.1000

sqoop 1.4.6

oozie 4.2.0

请帮助我解决错误和问题，为什么sqoop命令在shell中正确运行，但是在oozie工作流程中却有错误？

答案 0 :(得分：0)

我不知道这是否是罪魁祸首。我一年前在HDP中使用Sqoop 1.4.x遇到了此问题，它显示死于一些不相关的失败原因。

从命令行在sqoop命令下运行时，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Oozie Sqoop操作运行相同的命令时，它不应像下面那样使用单引号（'）。

<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>

答案 1 :(得分：0)

我通过以下方法解决了我的问题：

1-在工作流.xml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，然后将hive-site.xml和tez-site.xml放在其中（从/etc/hive/2.6.5.0-292/0上传hive-site.xml /和tez-site.xml从/etc/tez/2.6.5.0-292/0/到hdfs上的lib文件夹）

根据上面的工作流定义两个文件（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具有指定的以下属性。

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