CDH 5.3 and Sqoop2 startup and use error

avatar
Explorer

Hello.

 

I had a CDH 5.1.3 installation where I was able to use the Sqoop2 client to import data into Hive and HBase. After upgrading to CDH 5.3 I am unable to get neither the Sqoop2 service to start successfully, nor am I able to use the Sqoop2 client. What do I need to do to get this to work as it did before the upgrade?

 

The errors reported in /var/log/sqoop2/catalna log are as follows:

... ... ...

Jan 20, 2015 4:10:54 PM org.apache.tomcat.util.digester.Digester endElement
WARNING:   No rules found matching 'HTML/BODY'.
Jan 20, 2015 4:10:54 PM org.apache.tomcat.util.digester.Digester endElement

SEVERE: Cannot start server. Server instance is not configured.

 

 

And, the Sqoop2 client throws an exception, and following is the output it displays:

For anyone else who may experience this:

The cause was a HSQLDB jar file present on the server outside of CDH installation and which was installed as part of another software. Removing this Jar file allowed Sqoop to import files from Sql Server (and MySql also). So problem solved.

Also I should add:

- I have tried first by upgrading CDH 5.1.3 to CDH 5.3. When I could not get Sqoop2 to work I performed a full CDH install.

- All the other services (HDFS, Hive, Hue, HBase, Solr, Spark, Impala)  that I have configured seem to be up and functioning properly.

- I have tried to remove the Sqoop2 service and add it again.

In attempting to analyze the problem I recreated a similar setup on another hardware. And in this setup Sqoop seems to start properly. The question then becomes how do I analyze the problem? What other logs are relevant?

The error "error parsing conf core-default.xml" seems to suggest that your
hadoop client configuration is malformed. Can you go through your hadoop
configuration and ensure that it's all proper XML please?

Thanks for your response.

 

The Sqoop2 client errors, I suspect, are the consequence of a problem somewhere else. Comparing with two setups where I attempted the same I do not find core-default.xml file anywhere on any of the file systems. Isn't the successful install of Sqoop2 service be a pre-requisite for the client to function?

 

At this time I am inclined to reinstall the base OS and install CDH on it. So the following is only to provide info that may help analyze and  improve debuggability of CDH in this aspect of installation, that the reported info does not seem to help identify the cause of the problem.

 

Following is reported by the installer when it installs Sqoop2 service.

 

Service did not start successfully; not all of the required roles started: Service has only 0 Sqoop 2 Server roles running instead of minimum required 1.
Supervisor returned FATAL. Please check the role log file, stderr, or stdout.

With CDH 5.3 reinstalled on a fresh Ubuntu 14.04 installation without any errors. But the Sqoop scripts/commands that worked with CDH 5.1 now do not work. The logged output indicates the SqlServer JDBC driver is not chosen by Sqoop. Sqoop incorrectly chooses Hsql driver even though the JDBC URL specifies sqlserver.  I have placed a copy of the SqlServer JDBC driver in /var/lib/sqoop, /var/lib/sqoop2 as well as in /opt/cloudera/parcels/CDH-5.3.0-1.cdh5.3.0.p0.30/jars.

 

As an experiment I also tried to using Sqoop2 also. But add link fails. I have posted the output at the end of this post.

 

What do I need to do to make this work?

 

 

The command is as below:

sqoop import \
    --driver com.microsoft.sqlserver.jdbc.SQLServerDriver \
    --connect jdbc:sqlserver://sqlserver:1433\;databaseName=dbname \
    --username sa --password thepasswd \
    --direct \
    --num-mappers 1 \
    --hive-import \
    --table person\
    --map-column-hive row_timestamp=timestamp \
    --verbose

 

The output of the command is below:

Thank you for providing the solution, @arund

Hey, I have encountered the same issue, and I found one path including this hsqldb.jar file and two outside of CDH:
/opt/cloudera/parcels/CDH-5.3.0-1.cdh5.3.0.p0.30/lib/hadoop/client-0.20/hsqldb.jar

/usr/share/java/hsqldb.jar

/usr/local/remote/packages/fortify_360_remote/2.6.0/PTA/Core/lib/hsqldb.jar

Should I remove both the two out of CDH? the last one is a Read-only directory, how did you do it?

Thanks

In my case removing the non CDH HSQDLDB Jar files was acceptable to me. But in general I suppose this could be corrected so that CDH does not use the Jar files that are elsewhere. Perhaps you could make this a suggestion in appropriate forum / ticket system at Cloudera.
