在build一個Cube，大概進行到第二步的時候
出現如下異常:

解決方案在這里:
https://issues.apache.org/jira/browse/KYLIN-1021
大意是:重新整理關於本地磁盤而不是HDF中JAR文件的問題，是的，Hadoop/Hive/HBase JAR應該存在於Hadoop群集的每台計算機上的本地磁盤中，位置相同；Kylin不會上載這些JAR；請檢查並確保Hadoop群集的一致性。
換句話說，集群中的其他主機的HBase目錄下的lib找不到某些jar包，集群中所有機器都要在同一位置存在這些jar包。所以我用集群分發命令把這些jar分發了：
[user@node-name hbase-1.3.1]$ bash xsync lib
