| |
| Overall Status |
| |
| This is the fifth public release of Chukwa, a log analysis framework on top of Hadoop |
| and HBase. Chukwa has been tested at scale and used in some production settings, and |
| is reasonably robust and well behaved. For instructions on setting up Chukwa, see the |
| administration guide and the rest of the Chukwa documentation. |

| |
| * New Chukwa Parquet file format. |

| |
| * There have been a number of bug fixes and code cleanups since the last release; |
| check the changelog and JIRA for details. |
| |

| |
| Chukwa relies on Java 1.6, and requires maven 3.0.3 to build. |
| The back-end processing requires Hadoop ${hadoopVersion}, HBase ${hbaseVersion}+, and Solr ${solrVersion}+. |
| |
| Known Limitations |
