{code}
You will receiver email like this :

> Issue Type: Improvement
> Reporter: Liu Shaohui

> Kylin has many inner meta data and outer dependencies. There may be
> inconsistent for bugs or failures. It's better to have a a health check job
> to find these inconsistent issues in advance。
> The inconsistent issues we found in our clusters are followings
> * {color:#808080}the cubeid data not exist for cube merging{color}
> * {color:#808080}hbase table not exist or online for a segment{color}
> * {color:#808080}there are holes in cube segments(The build of some days
> failed, but user not found it){color}
> * {color:#808080}Too many segment(hbase tables){color}
> * {color:#808080}metadata of stale segment left in cube{color}
> * {color:#808080}Some cubes have not be updated/built for a long time{color}
> * {color:#808080}Some important parameters are no set in cube desc{color}
> * {color:#808080}...{color}
> Suggestions are welcomed, thanks~
