This weekly blog post +covers ongoing development and news in the Apache Kudu project. + +<!--more--> + +## Project news + +* The first release candidate for Kudu 1.1.0 is [now available](http://mail-archives.apache.org/mod_mbox/kudu-dev/201611.mbox/%3CCADY20s7ZKZkPmUEcTexW%3D%2B_%2BLnDY2hABZg0-UZD3jvWAs9-pog%40mail.gmail.com%3E). + + Noteworthy new features/improvements: + * The Python client has been brought to feature parity with the C++ and Java clients. + * IN LIST predicates. + * Java client now features client-side tracing. + * Kudu now publishes jar files for Spark 2.0 compiled with Scala 2.11. + * Kudu's Raft implementation now features pre-elections. In our tests this has greatly + improved stability. + + Community developers and users are encouraged to download the source + tarball and vote on the release. + + For more information on what's new, check out the + [release notes](https://github.com/apache/kudu/blob/branch-1.1.x/docs/release_notes.adoc). + *Note:* some links from these in-progress release notes will not be live until the + release itself is published. + +* On November 7th, the Kudu PMC announced that Jordan Birdsell, from State Farm, had been voted + in as a new committer and PMC member. + + Jordan's contributions include extensive work on the python client, throwing it some much needed + love, and bringing it to feature parity with the other clients. + + Besides his extensive code contributions Jordan has also been active in reviewing other + developer's patches and helping the community in general, on slack and other channels. + + Jordan has been doing great work and the Kudu PMC was pleased to recognize his contributions + with committership. + +* Mike Percy will be presenting Kudu Wednesday 16th November at [Apache Big Data Europe, in Seville](https://apachebigdataeu2016.sched.org/). + +* Congratulations to Haijie Hong for his [first contribution to Kudu!](https://gerrit.cloudera.org/#/c/4822/). + Haijie fixed some edge cases in BitWriter that were blocking RLE usage for 64 bit types. + +* Congratulations to Maxim Smyatkin for his [first contributions to Kudu!](https://gerrit.cloudera.org/#/q/Maxim). + Maxim has contributed several patches helping with debug and cleanup. + +## Development discussions and code in progress + +* A lot of progress has been done towards the goals that were set in the scope docs introduced in + the last couple of posts. Specifically: + + * Dan Burkert, Todd Lipcon and Alexey Serbin have doubled down on the security effort. They have + been working on enabling Kerberos authentication and rpc encryption. The [security scope doc](https://docs.google.com/document/d/1cPNDTpVkIUo676RlszpTF1gHZ8l0TdbB7zFBAuOuYUw/edit#heading=h.gsibhnd5dyem) + has been updated with the latest plans for security and many patches have been merged already. + + * David Alves has continued the work on [consistency](https://s.apache.org/7VCo). Up for review + and partially pushed is a patch series to address row history loss if a row is deleted and then + re-inserted. Also in progress is work to make sure that scans at a snapshot from followers + always return same data as if they were executed on the leader. This helps with Read-Your-Writes + when reading from lagging replicas. + + * Adar Dembo has been making good progress [addressing issues seen with the LogBlockManager](https://s.apache.org/uOOt). + A series of patches have been merged with various fixes to block managers in general and to the + log block manager in particular. + + * Dinesh Bhat has been working on improving the manual recovery tools for Kudu. Namely, he has + added a tool to force a remote replica copy to a destination server, and a tool to delete a + local replica of a tablet. The latter is useful when a tablet cannot come up due to bad state. + + * Jean-Daniel Cryans has implemented RPC tracing for the java client, greatly improving + debuggability. JD also has added ReplicaSelection to the java client, allowing to perform + scans on replicas other than the leader, which should be of great help for load-balancing. + + * Besides the feature parity contributions, Jordan Birdsell has laid out a + [roadmap for Python client work](http://mail-archives.apache.org/mod_mbox/kudu-dev/201611.mbox/%3CCAGaaj_VKfB4mhu6eExHCWo0%3D6Qd0HFWy7bg9e39JgOaFPGJ1nQ%40mail.gmail.com%3E) + for the 1.2 release. Feedback from other Python client users is certainly appreciated. + +Want to learn more about a specific topic from this blog post?
