I have problem when use sqoop actin with hcatalog in ambary-views.

The following command run in shell correctly and it works so good.

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 --hcatalog-table 'daily_tr'

image of shell:

but when I define sqoop action in ambary-views workflow manager with this command I have an error following:

Image of ambary-views workflow manager:

For solve this error I do the following:

under folder in which workflow.xml is, i create folder lib and put there all hive jar files from sharedlibDir(/user/oozie/share/lib/lib_201806281525405/hive

My goal was to do that, components recognize hcatalog jar files and classpath so I’m not sure for that, and maybe I shouln’t do that and do different solution for this error

Anyway after do that the error has been changed following:

my HDP version:

please help me to solve errors and issue and why the sqoop command work correctly in shell but in ambari-views workflow manager has error?

ahajitorab · ‎12-30-2018

I solved my problem by the following:

1- use ( --hcatalog-home /usr/hdp/current/hive-webhcat ) in command tag in workflow.xml:

<?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- on the hdfs create lib folder beside workflow.xml and put hive-site.xml and tez-site.xml to that (upload hive-site.xml from /etc/hive/2.6.5.0-292/0/ and tez-site.xml from /etc/tez/2.6.5.0-292/0/ to lib folder on hdfs)

according to above in workflow define two files (hive-site.xml and tez-site.xml)

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

3- define the following property in job.properties file:

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

4- Make sure oozie-site.xml under /etc/oozie/conf has the following property specified.

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