| <div class="entry-content"> |
| <p>Welcome to the nineteenth edition of the Kudu Weekly Update. This weekly blog post |
| covers ongoing development and news in the Apache Kudu project.</p> |
| |
| <!--more--> |
| |
| <h2 id="development-discussions-and-code-in-progress">Development discussions and code in progress</h2> |
| |
| <ul> |
| <li> |
| <p>After a couple months of work, Dan Burkert finished |
| <a href="https://gerrit.cloudera.org/#/c/3648/">adding add/remove range partition support</a> |
| in the C++ client and in the master.</p> |
| |
| <p>Dan also posted a patch for review which <a href="https://gerrit.cloudera.org/#/c/3854/">adds support for this |
| feature</a> to the Java client. Dan is |
| expecting that this will be finished in time for the upcoming Kudu 0.10.0 |
| release.</p> |
| |
| <p>Misty Stanley-Jones started working on <a href="https://gerrit.cloudera.org/#/c/3796/">documentation for this |
| feature</a>. Readers of this |
| blog are encouraged to check out the docs and provide feedback!</p> |
| </li> |
| <li> |
| <p>Adar Dembo also completed fixing most of the issues related to high availability |
| using multiple Kudu master processes. The upcoming Kudu 0.10.0 release will support |
| running multiple masters and transparently handling a transient failure of any |
| master process.</p> |
| |
| <p>Although multi-master should now be stable, some work remains in this area. Namely, |
| Adar is working on a <a href="https://gerrit.cloudera.org/#/c/3393/">design for handling permanent failure of a machine hosting |
| a master</a>. In this case, the administrator |
| will need to use some new tools to create a new master replica by copying data from |
| an existing one.</p> |
| </li> |
| <li> |
| <p>Todd Lipcon started a |
| <a href="https://mail-archives.apache.org/mod_mbox/incubator-kudu-dev/201607.mbox/%3CCADY20s5WdR7KmB%3DEAHJwvzELhe9PXfnnGMLV%2B4t%3D%3Defw%3Dix8uw%40mail.gmail.com%3E">discussion</a> |
| on the dev mailing list about renaming the Kudu feature which creates new |
| replicas of tablets after they become under-replicated. Since its initial |
| introduction, this feature was called “remote bootstrap”, but Todd pointed out |
| that this naming caused some confusion with the other “bootstrap” term used to |
| describe the process by which a tablet loads itself at startup.</p> |
| |
| <p>The discussion concluded with an agreement to rename the process to “Tablet Copy”. |
| Todd provided patches to perform this rename, which were committed at the end of the |
| week last week.</p> |
| </li> |
| <li> |
| <p>Congratulations to Attila Bukor for his first commit to Kudu! Attila |
| <a href="https://gerrit.cloudera.org/#/c/3820/">fixed an error in the quick-start documentation</a>.</p> |
| </li> |
| </ul> |
| |
| <h2 id="news-and-articles-from-around-the-web">News and articles from around the web</h2> |
| |
| <ul> |
| <li>The New Stack published an <a href="http://thenewstack.io/apache-kudu-fast-columnar-data-store-hadoop/">introductory article about Kudu</a>. |
| The article was based on a recent interview with Todd Lipcon |
| and covers topics such as the origin of the name “Kudu”, where Kudu fits into the |
| Apache Hadoop ecosystem, and goals for the upcoming 1.0 release.</li> |
| </ul> |

| aware of some Kudu news we missed, let us know so we can cover it in |
