At @opencore we love to travel and see new places. So we have decided to offer a discount to customers in countries that we have not yet visited. Check out our map at bit.ly/2Q3gPtK ! Preferred treatment is given to warm, sunny countries with nice beaches ;)

We from @opencore together with our friends from @inovexgmbh (hi @data_hpz) and others are now collaborating on open source training material at the Apache Foundation in the new Apache Training (incubating) project! Contact us if you've got questions or want to contribute!

New blog post: We created Parcel & CSD for #apacheknox for #cloudera manager: opencore.com/blog/2018/11/kn… Feedback welcome!

We're also building a Parcel and CSD for #Cloudera Manager for #apachenifi and looking for sponsorship Unfortunately this also needs some work on NiFi itself. e.g.: apache-nifi-developer-list.3… issues.apache.org/jira/brows… issues.apache.org/jira/brows… issues.apache.org/jira/brows…

The next sponsorship we're looking for is for work on a Parcel and CSD for @cloudera Cloudera Manager for #apacheknox. We've started work here github.com/opencore/knox-clo… but unfortunately it requires more work as outlined here lists.apache.org/thread.html… Anyone interested?

We are looking for sponsorship for some #opensource projects! First is the implementation of Transparent Data Encryption (TDE) for #apachekafka @SoenkeLiebau has written a proposal here: cwiki.apache.org/confluence/… Reach out if you're interested in sponsoring work on this feature

Sönke has written a new blog post on his Ansible scripts to create SSL/TLS certificates and Java Keystores mostly for dev environments using Ansible scripts. opencore.com/blog/2018/8/key…

A blog post about our journey to debug a problem starting YARN. It's a fun story from the source code of Hadoop to OpenJDK, Linux and Python to end up in SSSD land: opencore.com/blog/2018/7/sss…

Another new blog post, part 2 of how we got started on #Azure. This one talks about the non-technical problems we faced opencore.com/blog/2018/6/clo… And a second blog post with a few generic updates (#conference talks, #trainings, #jobs etc.) opencore.com/blog/2018/6/con…

And on Wednesday 12:40 (Kesselhaus) @lars_francke will be talking at the @Fossbckstg #FOSSback conference also in Berlin on his experiences in the open source world foss-backstage.de/session/ha…

Our @SoenkeLiebau will be giving a talk today at 12:20 (Palais Atelier) on Kafka Security berlinbuzzwords.de/18/sessio… at the @berlinbuzzwords #bbuzz conference. If you've got questions just come up and talk to him!

By the way: We now also offer training! The first courses are covering the Hadoop ecosystem basics, one on HBase (given by a HBase committer) and another for Kafka. And we're also hiring. If you're interested reach out to us.

We've got another new blog post to share. This is a bit different: It tells a brief story on how we got started on Azure and which difficulties we faced: opencore.com/blog/2018/5/get…

Another new blog post It's about the "spark.sql.hive.metastore.sharedPrefixes" option in Spark, relevant if you ever see an IllegalArgumentException "is not visible from class loader". Hopefully you'll never need it :) Enjoy: opencore.com/blog/2018/3/spa…
