hbase启动的时候出现java.lang.NoClassDefFoundError: org/apache/htrace/SamplerBuilder
原因是htrace包找不到应该将/opt/module/hbase-2.1.9/lib/client-facing-thirdparty目录下的htrace-core-3.1.0-incubating.jar拷贝到/opt/module/hbase-2.1.9/lib/cp /opt/module/hbase-2.1.9/lib/client-facing-thirdparty/htrace-core-3.1.0-incubating.jar /opt/module/hbase-2.1.9/li
