There are not much logging in the provided WARN message to identify the root cause of the issue.

But few things we can check like the Postgres JDBC Driver is jar installed in Oozie sharelib or not? And Sqoop client is installed on all the nodes properly.

my sharelib is:

oozie admin -oozie http://ambari.4linux.com.br:11000/oozie -shareliblist[Available ShareLib]
hive
distcp
mapreduce-streaming
spark
oozie
hcatalog
hive2
sqoop
pig
spark_orig<br>

but i have the postgres.jar inside sqoop folder

When i try to execute anyone command with user oozie i have thist error:

But when i execute anyone command with root, the command finish with success.

@Guilherme Colla

As mentioned earlier the symptoms indicates that you have not placed the Postgres SQL driver inside your OOzie sharedlib.

can you please try that. May be you can try putting the Postgresql driver jar inside the "/user/oozie/share/lib/lib*/sqoop" on hdfs.

Then check:

# hdfs fs -ls /user/oozie/share/lib/sqoop/

.

@Jay Kumar SenSharma

I have the postgres jar inside te /user/oozie/share/lib/*/sqoop

hdfs dfs -ls /user/oozie/share/lib/*/sqoop | grep sql

@Guilherme Colla

After putting that Jar in the "/user/oozie/share/lib/lib_20171030154340/sqoop/postgresql-9.2-1002.jdbc4.jar" location have you run the "sharelibupdate" command after putting the Jar there?

# oozie admin -oozie http://$HOSTNAME:11000/oozie -sharelibupdate 

.

[#8]

@Jay Kumar SenSharma

yes, after i put jar i run the sharelibupdate

[#9]

@Guilherme Colla

Please check on your HDFS where your "workflow.xml" is present, create "lib" directory there and put the postgresql jdbc driver jar inside that directory (on HDFS).

.

[#10]

@Guilherme Colla

Can you also check if your "job.properties" has included the lib?

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