Subject [jira] [Commented] (HDFS-5274) Add Tracing to HDFS
Date Wed, 16 Apr 2014 19:38:20 GMT

    [ https://issues.apache.org/jira/browse/HDFS-5274?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13971846#comment-13971846
] 

Elliott Clark commented on HDFS-5274:
-------------------------------------

Please don't add htrace-zpikin as a dependency.  That version of thrift pulled in is very
old and we don't want to have classpath issues because of a new feature.

> 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.
