解决的过程及方案 1、经多方查找发现 Kylin源码github项目最新的master分支已经支持更改存储的hbase的默认namespace但是官方对外发布的最新安装包才更新到Kylin-2.1版本且最新源码并没有经过生产的验证不敢冒然部署于是想办法在现有的版本上重新编译源码、打包。 2、经多方搜索确认更改hbase namespace的commit是kylin-2846于是查找相关实现的细节。
解决思路 1、首先按照github上提供的修改方法更改了https://github.com/apache/kylin/commit/ffcbdb7f4288fa6011f018163bdce9602415cf10 中的五个类重新编译打包执行到convert cuboid Data to HFile这一步的时候抛出异常找不到Hbase表
org.apache.hadoop.hbase.TableNotFoundException:ISW:KYLIN_F3KD3ZC1LU
at org.apache.hadoop.hbase.client.HBaseAdmin.getTableDescriptor(HBaseAdmin.java:575)
而这时我在hbase shell指定的namespace查看已经生成了hbase表为什么会找不到呢继续查找原因 2、继续找Kylin-2846相关的内容发现有人遇到同样的问题地址https://issues.apache.org/jira/browse/KYLIN-2846 原来github上给出的代码少了很关键的一步

修改完后core-common, core-cure, storage-hbase三个目录重新打jar包覆盖原Kylin安装目录KYLIN_HOME/tomcat/webapps/kylin.war下对应的jar包重启Kylin问题解决。
