Re: NoSuchMethodError using zipkin with hbase 0.98.5

[Masatake Iwasaki]

Hi Abhishek,

hbase-0.98.5 is built against htrace-2.04.
Because htrace-2.04 is not compatible with 3.0.4,
you shold use htrace htrace-2.04 in this case.

The configuration property is slightly different for htrace-2.04.
(not org.htrace.impl but org.cloudera.htrace.impl)::

  <property>
    <name>hbase.trace.spanreceiver.classes</name>
    <value>org.cloudera.htrace.impl.ZipkinSpanReceiver</value>
  </property>

You also need to fix pom.xml of htrace-zipkin
in order to build jar-with-dependency by maven-assembly-plugin.
I show you the build procedure and diff of pom.xml below.
It worked for me with newest zipkin and hbase-0.98.5.

git clone https://github.com/cloudera/htrace
cd htrace
git checkout htrace-2.04
cd htrace-zipkin/
vim pom.xml
mvn compile assembly:single
cp target/htrace-zipkin-2.04-jar-with-dependencies.jar 
/path/to/hbase-0.98.5-hadoop2/lib/

I am sorry to be late to respond.
Thanks for reporting this.

You need to download Zipkin from https://github.com/twitter/zipkin
and run its services if you use ZipkinSpanReceiver.
Zipkin has its own UI.
The viewer in htrace-hbase is just for HBaseSpanReceiver.

Thanks Ted.

I excluded slf4j from thrift as you suggested and then I had to also add
slf4j 1.6.4 as dependency to avoid package org.slf4j missing error.

I also required to compile htrace-core and add htrace-core-3.0.4.jar, which
is not documented in http://hbase.apache.org/book/tracing.html

I am now able to start my hbase services.

However, I am not able to compile htrace-hbase which has the zipkin viewer.
Is there any other way to see the zipkin traces?

Thanks
Abhishek
