+title: Apache Kudu Weekly Update July 26, 2016
+author: Jean-Daniel Cryans
+---
+Welcome to the eighteenth edition of the Kudu Weekly Update. This weekly blog post
+covers ongoing development and news in the Apache Kudu project.
+
+<!--more-->
+
+## Project news
+
+* Kudu has graduated from the Apache Incubator and is now a Top-Level Project! All the details
+ are in this [blog post](http://kudu.apache.org/2016/07/25/asf-graduation.html).
+ Mike Percy and Todd Lipcon made a few updates to the website to reflect the project\u2019s
+ new name and status.
+
+## Development discussions and code in progress
+
+* Dan Burkert contributed a few patches that repackage the Java client under `org.apache.kudu`
+ in place of `org.kududb`. This was done in a **backward-incompatible** way, meaning that import
+ statements will have to be modified in existing Java code to compile against a newer Kudu JAR
+ version (from 0.10.0 onward). This stems from [a discussion](http://mail-archives.apache.org/mod_mbox/kudu-dev/201605.mbox/%3CCAGpTDNcJohQBgjzXafXJQdqmBB4sL495p5V_BJRXk_nAGWbzhA@mail.gmail.com%3E)
+ initiated in May. It won\u2019t have an impact on C++ or Python users, and it isn\u2019t affecting wire
+ compatibility.
+
+* Still on the Java-side, J-D Cryans pushed [a patch](https://gerrit.cloudera.org/#/c/3055/)
+ that completely changes how Exceptions are managed. Before this change, users had to introspect
+ generic Exception objects, making it a guessing game and discouraging good error handling.
+ Now, the synchronous client\u2019s methods throw `KuduException` which packages a `Status` object
+ that can be interrogated. This is very similar to how the C++ API works.
+
+ Existing code that uses the new Kudu JAR should still compile since this change replaces generic
+ `Exception` with a more specific `KuduException`. Error handling done by string-matching the
+ exception messages should now use the provided `Status` object.
+
+* Alexey Serbin\u2019s [patch](https://gerrit.cloudera.org/#/c/3619/) that adds Doxygen-based
+ documentation was pushed and the new API documentation for C++ developers will be available
+ with the next release.
+
+* Todd has made many improvements to the `ksck` tool over the last week. Building upon Will
+ Berkeley\u2019s [WIP patch for KUDU-1516](https://gerrit.cloudera.org/#/c/3632/), `ksck` can
+ now detect more problematic situations like if a tablet doesn\u2019t have a majority of replicas on
+ live tablet servers, or if those replicas aren\u2019t in a good state.
+ `ksck` is also [now faster](https://gerrit.cloudera.org/#/c/3705/) when run against a large
+ cluster with a lot of tablets, among other improvements.
+
+* As mentioned last week, Dan has been working on [adding add/remove range partition support](https://gerrit.cloudera.org/#/c/3648/)
+ in the C++ client and in the master. The patch has been through many rounds of review and
+ testing and it\u2019s getting close to completion. Meanwhile, J-D started looking at adding support
+ for this functionality in the [Java client](https://gerrit.cloudera.org/#/c/3731/).
+
+* Adar Dembo is also hard at work on the master. The [series](https://gerrit.cloudera.org/#/c/3609/)
+ [of](https://gerrit.cloudera.org/#/c/3610/) [patches](https://gerrit.cloudera.org/#/c/3611/) to
+ have the tablet servers heartbeat to all the masters that he published earlier this month is
+ getting near the finish line.
