Hey, I was originally researching options to work on ACCUMULO-1197. Basically, it was a bid to pass trace functionality through the DFSClient. I discussed with the guys over there on implementing a Google Dapper-style trace with HTrace. The guys at HBase are also trying to achieve the same HTrace integration [HBASE-6449]
But, that meant adding stuff to the RPC in HDFS. For a start, we've to add a 64-bit span-id to every RPC with tracing enabled. There's some more in the original Dapper paper and HTrace documentation. I was told by the Accumulo people to talk with and seek help from the experts at HDFS. I'm open to suggestions. Additionally, I'm participating in a Joint Mentoring Programme by Apache which is quite similar to GSoC. Luciano Resende (Community Development, Apache) is incharge of the programme. I'll attach a link. The last date is 19th July. So, I'm pretty tensed without any mentors :( [1] https://issues.apache.org/jira/browse/ACCUMULO-1197 [2] https://issues.apache.org/jira/browse/HDFS-4680 [3] https://github.com/cloudera/htrace [4] http://community.apache.org/mentoringprogramme-icfoss-pilot.html [5] https://issues.apache.org/jira/browse/HBASE-6449 Thank you, Sreejith R
