Subject [jira] [Commented] (ACCUMULO-898) look into replacing cloudtrace
Date Tue, 21 Oct 2014 20:17:35 GMT

    [ https://issues.apache.org/jira/browse/ACCUMULO-898?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14178996#comment-14178996
] 

Eric Newton commented on ACCUMULO-898:
--------------------------------------

I'm having difficulty with the IT's.  For example:

{noformat}
$ mvn -Dhadoop.version=3.0.0-SNAPSHOT package -Dtest=ShellServerIT\#trace -DfailIfNoTests=false
{noformat}

I'm working off my own changes based on the posted patch.  The basic test works when I emulate
it manually in the shell against hadoop 3.0.0 (awesome!), but the IT fails.  I don't see any
of the processes picking up the config to use the ZooTraceClient class.

 zipkin has a reasonable visualization, and seems to work with thrift.  We should look into
replacing our tracing with one of these.
