折腾了半天：

其实呢，这个错误。哎
按顺序执行：
create table test(
id integer not null primary key,
name varchar,
age integer
);
upsert into test values(1,'wjc',18);
upsert into test values(2,'xb',19);
create index idx_test_name on test(name);
upsert into test values(3,'xm',28); -- 这一步报错，只有删除二级索引才正常。
最终是版本兼容性的问题：
目前phoenix5.0 是最新的版本，支持 HBase2.0
前人挖坑，后人填。哈哈哈。
原来项目使用的是：HBase2.0.1 ，请注意 多了个.1
你没看错，Phoenix5.0 不兼容 HBase2.0.1。所以更新索引报错了。
解决方法： 将环境中 HBase2.0.1 ，全部修改为 HBase2.0.0，替换后测试正常！！
