Hortonworks, eBay and Scaled Risk have been collaborating in improving the mean time to recovery in HBase and after long testing performed at eBay, some results are now available for 2 scenarios:
- Node/RegionServer failures while writing
- Node/RegionServer failures while reading

In 4 years of writing this blog I haven’t seen such a prolific month:
- Apache Hadoop 2.2.0 (more links here)
- Apache HBase 0.96 (here and here)
- Apache Hive 0.12 (more links here)
- Apache Ambari 1.4.1
- Apache Pig 0.12
- Apache Oozie 4.0.0
- Plus Presto.
Actually I don’t think I’ve ever seen such an ecosystem like the one created around Hadoop.

- Uses Guice to load modules.
- Incorporates Jetty for Rest API and serving up UI.
- Pure Java build tool (Tablesaw)
- UI uses Flot and is client side rendered.
- Ability to customize UI.
- Relative time now includes month and supports leap years.
- Modular data store interface supports:
- H2 (For development)
- Milliseconds data support when using Cassandra.
- Rest API for querying and submitting data.
- Build produces deployable tar, rpm and deb packages.
- Linux start/stop service scripts.
- Made aggregations optional (easier to get raw data).
- Added abilities to import and export data.
- Aggregators can aggregate data for a specified period.
- Aggregators can be stacked or “piped” together.
Source code lives on GitHub. Let’s see where it goes.
