stack commented on HDFS-5274: ----------------------------- I put up a SNAPSHOT of the tracing jar w/ its groupId changed from org.cloudera.htrace to org.htrace. The version is currently 3.0-SNAPSHOT (all is the same except for the redone domain). If it works for you [~iwasakims], I'll make a release (if the former owners of this jar are good w/ my manglings). Thanks boss. > Add Tracing to HDFS > ------------------- > > Key: HDFS-5274 > URL: https://issues.apache.org/jira/browse/HDFS-5274 > Project: Hadoop HDFS > Issue Type: New Feature > Components: datanode, namenode > Affects Versions: 2.1.1-beta > Reporter: Elliott Clark > Assignee: Elliott Clark > Attachments: HDFS-5274-0.patch, HDFS-5274-1.patch, HDFS-5274-2.patch, > HDFS-5274-3.patch, HDFS-5274-4.patch, HDFS-5274-5.patch, HDFS-5274-6.patch, > HDFS-5274-7.patch, HDFS-5274-8.patch, HDFS-5274-8.patch, Zipkin Trace > a06e941b0172ec73.png, Zipkin Trace d0f0d66b8a258a69.png, ss-5274v8-get.png, > ss-5274v8-put.png > > > Since Google's Dapper paper has shown the benefits of tracing for a large > distributed system, it seems like a good time to add tracing to HDFS. HBase > has added tracing using HTrace. I propose that the same can be done within > HDFS. -- This message was sent by Atlassian JIRA (v6.1.5#6160)
