The Hadoop project currently has various hooks with HT= race. It seems in some cases (eg HDFS-13702) these hooks have had measurabl= e performance overhead. Given these two factors, I think we should consider= removing the HTrace integration. If there is someone willing to do the wor= k, replacing it with OpenTracing might be a better choice since there is an= active community. -- This message was sent by Atlassian JIRA (v7.6.3#76005) --------------------------------------------------------------------- To unsubscribe, e-mail: common-issues-unsubscribe@hadoop.apache.org For additional commands, e-mail: common-issues-help@hadoop.apache.org
