我正在尝试用start-hbase.sh启动hbase，但是，出现错误： java.lang.ClassNotFoundException: org.apache.htrace.SamplerBuilder. 我尝试添加了各种 .jar ，但没有任何效果。我使用的是hadoop3.11和hbase 2.10，这里是错误日志的结尾。

hbase和hadoop之间似乎存在兼容性问题，我恢复使用hadoop2.9.1和hbase 1.2.6以及jdk1.8.0

HBAS2.1.0发布使用HTrink，这是一个孵化的Apache基金会项目。
hbase中有一个用于第三方库的文件夹
lib文件夹，client-facing-thirdparty. 你需要复制htrace-core-3.1.0-incubating.jar从那里到hbase lib目录(（见参考文献）cloudera社区还有另一个解决方案，它可以更改配置，而不是手动添加库。

hbase 2.1.4没有
htrace-core-3.1.0-incubating.jar在client-facing-thirdparty您需要从2.1.3中复制或从下载https://mvnrepository.com/artifact/org.apache.htrace/htrace-core
