Hi Folks, Right now we are able to initiate TRACE within Log4j file in Nutch 2.X [0]. Nutch 2.X offer storage abstraction for storage of Webpage and Host data through use of Apache Gora. Gora backend support includes
- Apache Avro 1.7.6 - Apache Hadoop 1.2.1 and 2.5.2 - Apache HBase 0.98.8-hadoop2 - Apache Cassandra 2.0.2 - Apache Solr 4.10.3 - MongoDB 2.6.X - Apache Accumlo 1.5.1 Parts of the Nutch 2.X search stack include Nutch, Gora, optionally Solr and/or Elastic Search for indexing context and optionally Hadoop for running it all on. As a developer of Nutch and Gora am very keen to see a more verbose tracing mechanism (potentially with some visualization) for debugging our search stack deployments. Can I please kick off conversation on what the difference and benefits of H Trace are over log4j TRACE level logging. Once I understand the above, I would like to obtain advice on the integration points for having HTrace as the tracing mechanism for the stack I describe above.
