  • 解决kylin报错:java.lang.IllegalStateException

    一个kylin build job执行到第三步Extract Fact Table Distinct Columns时报错:

    2017-05-24 20:04:07,930 ERROR [pool-9-thread-3] common.MapReduceExecutable:127 : error execute MapReduceExecutable{id=a79c9625-39aa-4f17-8015-73b640558425-02, name=Extra
    ct Fact Table Distinct Columns, state=RUNNING}

            at java.lang.Thread.run(Thread.java:745)

    解决方案:找到执行这个build任务的kylin实例,reload metadata或重启kylin服务(不推荐),然后重新build.

    原因分析:执行build的job server内存中的Meta没有被更新,使用了缓存中的Meta执行build导致。
