I would potentially be interested in continue to be involved with HTrace as a subproject.
The vision behind HTrace was always to have a single trace system that unified all of Hadoop. So you could see what Accumulo was doing and how that affected HDFS, or what Phoenix was doing that affected HBase and HDFS, etc. etc. This has sort of been built several times internally by companies running services based on Hadoopy projects, but never really made its way into open source in a meaningful way. I thought we had a good shot at that, but maybe we needed to start earlier and have more resources. We especially lacked full-time developers and people to evangelize the client. I think it makes the most sense for HTrace to be a subproject of either Apache Hadoop or Apache Skywalking. Skywalking in particular seems interesting since its goals are very similar to HTrace's -- to be a one-stop shop including tracing clients, visualization, and storage. Perhaps HTraced could be useful to them for improving that "first 15 minute experience". It's easy to start up and doesn't require managing a separate storage or query system. I'm not so sure about HTrace being a subproject of Accumulo. It seems like Accumulo is really focused on being a storage system, not so much on being a platform. It would be weird for HBase or HDFS to depend on something that was a subproject of Accumulo, for example. best, Colin On Wed, Mar 14, 2018, at 17:35, Michael Wall wrote: > I am interested.
