[jira] [Updated] (HDFS-8088) Reduce the number of HTrace spans generated by HDFS reads
[ https://issues.apache.org/jira/browse/HDFS-8088?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ] Wei-Chiu Chuang updated HDFS-8088: -- Resolution: Won't Fix Status: Resolved (was: Patch Available) I'm going to resolve this one as won't fix since htrace is dead. However, [~smeng] please take a look at it and see if we can get the parity for opentracing. > Reduce the number of HTrace spans generated by HDFS reads > - > > Key: HDFS-8088 > URL: https://issues.apache.org/jira/browse/HDFS-8088 > Project: Hadoop HDFS > Issue Type: Improvement >Reporter: Colin P.
