kylin cube build error(hbase table is exists)

[小宇（王宇） <10...@qq.com>]

hello everyone!

I have a cube,every hour it build,But sometimes met a problem.That is on step #6(create Htable).

on the kylin ui.see my pic









open the log window see



clearly,table xxxx is exists,so I go to the base,see below pic



Strang thing happened,this table's create time is same to picture1's error time(2018-10-21 10:29:57),I guess the step is success,But it trigger twice.
So I go to see kylin soucecode(branch 2.3.x same,my server's kylin version is 2.3.1),create hbase table's real opt class is CubeHTableUtil



In my server log,I can't found create htable success log,But in this code,if create htable success it will print log(create hbase table xxx done.).So I can't found real reasion


Can anyone answer my doubts?

That code (disable and drop when already exists) is disabled for safety
reason; Because this case is a wrong situation, should alert the
administrator.

How many nodes in your Kylin cluster? How many nodes running job engine?

I didn't see such issue, so you may need dive into the logs, including
HBase logs for the clue.
