@Guilherme Colla

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.

@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/

@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

Re: Error when i try to import a table from postgres to hive

collamorelli — Tue, 07 Nov 2017 02:08:47 GMT

@Jay Kumar SenSharma

yes, after i put jar i run the sharelibupdate

@Guilherme Colla

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

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

Re: Error when i try to import a table from postgres to hive

collamorelli — Tue, 07 Nov 2017 02:15:03 GMT

@Jay Kumar SenSharma

My "job.properties" hasn't included the lib, i put the lib and the job failed.

I create a sqoop job in workflow manager and works, now i try to execute this command and the job failed, you can help me ?

sqoop import --connect jdbc:postgresql://10.0.0.78:5433/cr4prd --username ambari --password xxxxxx --table tb_con_contatos --hive-database cr4prd --hive-import -m1

Re: Error when i try to import a table from postgres to hive

jsensharma — Tue, 07 Nov 2017 02:22:42 GMT

@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).

Re: Error when i try to import a table from postgres to hive

jsensharma — Tue, 07 Nov 2017 02:25:15 GMT

@Guilherme Colla

sqoop import --connect jdbc:postgresql://10.0.0.78:5433/cr4prd --username ambari --password xxxxxx --table tb_con_contatos --hive-database cr4prd --hive-import -m1

If your above Standalone Sqoop command is failing with the missing driver error then you will need to place your postgresql jdbc driver inside the "/usr/hdp/current/sqoop-client/lib/"

Re: Error when i try to import a table from postgres to hive

collamorelli — Tue, 07 Nov 2017 02:29:45 GMT

@Jay Kumar SenSharma

In my path "/usr/hdp/current/sqoop-client/lib/" i hasn't the driver postgres, i put inside the path and run the job but the same failed.

@Guilherme Colla

I just tried the following command at my end and it seems to have worked with the following command set.

# cp /usr/lib/ambari-server/postgresql-9.3-1101-jdbc4.jar  /usr/hdp/current/sqoop-client/lib/

# su -l sqoop -c "sqoop  import --connect jdbc:postgresql://amb25101.example.com:5432/ambari --username ambari --password bigdata --table hosts  --hive-database default --hive-table ambari_hosts_hive --hive-import -m 1 --target-dir /apps/hive/warehouse/ambari_hosts_hive.db/ambari_hosts_hive"

Is your Postgressql Jar correct? I mean is it corrupted by any chance?

# grep 'org.postgresql.Driver' /usr/lib/ambari-server/postgresql-9.3-1101-jdbc4.jar

Binary file /usr/lib/ambari-server/postgresql-9.3-1101-jdbc4.jar matche

@Jay Kumar SenSharma

Thanks for your help.

I solved this problem as follows:

Create a sqoop job for extract data and load in HDFS
Using a hive job for execute a "load data inpath" for load data inside hive
