Re: Running UnitTests before submitting a patch

I'm not too familiar with the Maven Failsafe plugin, but I've been reviewing the timings of some 'client' unit tests and where the unit test framework spends it's time... Anything that uses HBaseTestingUtility and does something like... protected void setUp() throws Exception {

Re: HBase and Eclipse under Windows

I think adding a link to your blog from the developer section in the Hbase book would be the easiest thing. I'll add it. Is that reasonable? On 9/14/11 10:20 AM, "Michael Morello" wrote: >Hello, > >My purpose was to help people that want to hack HBase with Eclipse from >the >source code, w

Re: [DISCUSSION] Accumulo, another BigTable clone, has shown up on Apache Incubator as a proposal

There was a discussion over the weekend on the incubator dist-list about Accumulo and describing what was borrowed from Hadoop-core and Hbase. http://mail-archives.apache.org/mod_mbox/incubator-general/201109.mbox/%3C8 96611333.83615.1315154356465.javamail.r...@linzimmb04o.imo.intelink.gov%3E 5

Re: [DISCUSSION] Accumulo, another BigTable clone, has shown up on Apache Incubator as a proposal

That's a good point. But the fact that Apache HTTPD is implemented in C, and Tomcat is in Java I think is material. While they compete for web server users, they have very different implementations. If ASF had two active Java webserver communities and codebases (e.g., "Tomcat" and "Timdog") I

Re: [DISCUSSION] Accumulo, another BigTable clone, has shown up on Apache Incubator as a proposal

Just for conversation, if somebody approached ASF incubator with an idea for a framework called "ExtendedSleep" that claimed to be a Java relational-object mapping framework (instead of the crusty object-relational approach that the Hibernate mapping framework provides), would anybody take it seri

Re: [DISCUSSION] Accumulo, another BigTable clone, has shown up on Apache Incubator as a proposal

They apparently have a very strong relationship with HBase...;-) "Apache Brand Our interest in releasing this code as an Apache incubator project is due to its strong relationship with other Apache projects, i.e. Hadoop, Zookeeper, and HBase." It's disappointing that these guys watched HBa
