我正在尝试使用apache kylin构建我的第一个多维数据集,一切正常,直到最后一步出现错误:

java.lang.IllegalStateException: Can't get cube source record count.

根据这个问题https://github.com/kylinap/kylin/issues/101上面的错误是因为kylin试图在配置单元的输出中找到这个模式:“hdfs read:(\d+)hdfs write:(\d+)success”。
立方体构建教程的正确输出:github.com/kylinap/kylin/wiki/kylin-cube-build-and-job-monitoring-tutorial:

我在Kylin的输出看起来已损坏:

但是,当我检查配置单元日志时,它看起来正常:

我正在使用hortonworks沙盒2.2:

hadoop-2.6.0
hbase-0.98.12
hive-0.14.0
zookeeper-3.4.6

有人能告诉我为什么我的Kylin日志预览看起来像这样,首先这可能是最后一步错误的原因吗?

几天前,Kylin开发人员承诺绕过这种问题
https://github.com/apache/incubator-kylin/commit/a4692dba681bc2f136e02c64565639eb0080fcc9
因为有时hadoop可能无法获取counter,即使作业从现在开始成功,当无法获取多维数据集源时,kylin会给出警告而不是错误。
我要做的就是重建Kylin。
