hbase2.0.0 之上重编译phoenix-5.0.0

部分组件版本 hbase 2.1.0, hadoop 3.0.0。通过phoenix 构建在HBase上的一个SQL层,能让我们用标准的JDBC APIs而不是HBase客户端APIs来进行数据操作。

目前官方最高版本为基于hbase2.0的phoenix5.0版本，没有提供基于hbase2.1版本，故只能自己编译。

 

phoenix 代码

bin/目录是编译后的执行客户端，去src目录下载phoenix5.0.0-hbase2.0 tag代码, 打包编译没有问题。
将pom.xml中的hbase版本从2.0.0改到2.0.2，先进行小版本升级实验，mvn打包报错如下：

具体idea log如下

将hbase版本由2.0.0改为2.1.0，build提示CellComparatorImp构造方法参数问题，原来的compare方法用的是两参数方法，现在原来的方法设置了final属性，我这里改为三参数方法，但里面的默认值不变。修改后如下

this(new CellComparatorImpl(){
      @Override
      public int compare(Cell a, Cell b, boolean ignoreSequenceid) {
          return super.compare(a, b, true);
      }
  });

至此可以打包编译，很顺利没有其他问题

报错显示缺少htrace对应jar包，发现hbase 2.1.0版本引入htrace，缺这个包，需要自己拷贝到hbase/lib
