+This is the first formal release of Chukwa, an Apache Hadoop subproject dedicated to scalable log collection and processing. If you have large volumes of log data generated across a cluster, and you need to process them with MapReduce, Chukwa may be the tool for you.

+Installation instruction are in docs/admin.html. The release notes are in docs/releasenotes.html

<h3>Overall status</h3>
-This is the first public release of Chukwa, a log analysis framework on top of Hadoop. Chukwa has been tested at scale, and is reasonably robust and well behaved.
+This is the first public release of Chukwa, a log analysis framework on top of Hadoop. 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 <a href="http://hadoop.apache.org/chukwa/docs/current/admin.html">the administration guide</a> and the rest of the Chukwa documentation.
-Documentation is still sparse, and error reporting isn't adequately clear. For instructions on setting up Chukwa, see <a href="http://hadoop.apache.org/chukwa/docs/current/admin.html">the administration guide</a>.
+The collection components of Chukwa -- adaptors, agents, and collectors -- are approaching general-use quality. They've been fairly aggressively tested, and can be counted on to perform properly and recover from failures.
+
+HICC, the visualization component, is "beta" quality. It's been used succesfully at multiple sites, but it's still brittle. Work is ongoing. Documentation is still sparse, and error reporting isn't always sufficiently clear.
<h3>Requirements</h3>
Chukwa relies on Java 1.6
The back-end processing requires Hadoop 0.18+.
Collecting Hadoop logs and metrics requires Hadoop 0.20+.
-<h3>Bug fixes</h3>
-Innumerable bugs have been fixed; see the changes file for details.
-
-<h3>Major Changes:</h3>
-
-<ul><li>
-As of Chukwa 0.2, adaptor IDs are now arbitrary strings, instead of sequentially assigned integers. These IDs can be specified by the user. The agent control protocol has been modified slightly to accommodate this.
-</li><li>
-HICC now supports graphing the results of arbitrary SQL statements.
-</li> <li>
-Tools have been added to support bulk-loading old data.
-</li> <li>
-Support for processing Chukwa data with Pig
-</li>
-</ul>
-
<h3>Known Limitations</h3>
<ul> <li> HICC defaults to assuming data is UTC; if your machines run on local time, HICC graphs will not display properly until you change the HICC timezone. You can do this by clicking the small "gear" icon on the time selection tool.
