> Key: KYLIN-1423
> URL: https://issues.apache.org/jira/browse/KYLIN-1423
> Project: Kylin
> Issue Type: Bug
> Components: Web
> Affects Versions: v2.0
> Reporter: Shaofeng SHI
> Assignee: Zhong,Jason
>
> With v2.0, in a cube's "HBase" tab, it shows:
> {code}
> HTable: KYLIN_KDKGMXLZRJ
> Region Count: 2
> Size: 260.00000 MB
> Start Time: 2016-02-16 16:40:00
> End Time: 2016-02-16 20:40:00
> HTable: KYLIN_FR2EIUHZ28
> Region Count: 2
> Size: 0 bytes
> Start Time: 2016-02-16 20:40:00
> End Time: 2016-02-17 00:40:00
> ...
> Total Size: 873.00000 MB
> {code}
> Two issues about the "Size" display:
> 1) the size has 5 precision is not accurate at all because the nubmer after
> the point are all 0. Just "260 MB" is good. The same issue exists for "Total
> Size";
> 2) the second table shows "0 bytes" seems like an empty table, while it has
> many records; if the size is small or failed to get the size, show "N/A" or
> "less than 1 M" would be better than show "0 bytes"
