I am using hadoop 2.9.1 and hbase 2.1.0 at stand-alone local mode.
When I tried staring HBase 2.1.0 using sudo start-hbase.sh
at bin folder, I got below error:
Exception in thread "main" java.lang.NoClassDefFoundError: org/apache/htrace/core/HTraceConfiguration

This is my hbase-site.xml

When I tried to start HBase version 1.2.0 , it started successfully and hbase shell
was also accessible and CRUD operations were successful.
Hadoop and HBase path are set. Only by that , I was able to run HBase-1.2.0.
Only with HBase-2.1.0, this problem occurs.
Any help appreciated! Thanks in advance!
Related: Starting HBASE, java.lang.ClassNotFoundException: org.apache.htrace.SamplerBuilder
htrace-core-*-incubating.jar
was missing from some early versions of HBase 2.x
If the htrace-core
jar
is in $HBASE_HOME/lib/client-facing-thirdparty
copy the jar
to $HBASE_HOME/lib
, otherwise
Download the Jar from Maven here
and place into $HBASE_HOME/lib
You can see in HBase pom.xml
for version hbase 2.1
that htrace 4.2.0
is the correct version of the dependency.

Goodluck.
