Hi tianshuo,

Please re-download Kylin binary package, there was a mistake in building

You might be impacted by that.

A bug in kylin 2.0 beta might cause some dirty data. You can try this way:

1. stop Kylin, and then run "bin/metastore.sh backup"
2. reset metastore: "bin/metastore.sh reset"
3. restore: "bin/metastore.sh restore "
4. start Kylin

Re: Cube build error on Step 7 Build Base Cuboid Data

[lufeng]

Hi ShaoFeng

I think it’s not an empty segment problem because Kylin has also consider this 
situation. Maybe is an none file issue that Kylin is not checked. 

I have open a issue on Kylin JIRA. Please check it 
https://issues.apache.org/jira/browse/KYLIN-2590
