Does Kylin support percent function?

[陈光亮]

HI,
  sorry,my English very pool.
  I have some problem when I  do demo.
  I want take some fields to percent function.
  For example:  
  table1
  idhostpid
  1local321
  2local123
  3google 987
  4google 789
  SELECT (SUM(CASE  WHEN (host="local") then 1 else 0 end)/count(*)*100) as 
hostpercent FROM table1
  The sql result is 50%. Mysql or hive can do this,but i don't know does kylin 
support this action?
  please help me, thank you!

All, thanks for your patience with this problem. We have identified a potential 
solution for the problem of project admins not being able to add agents. We are 
discussing and testing internally at the moment and expect to have another 
update in a few hours.

[叶]

when build cube done . I execute query "select * from xxx" hits error below:

  org.apache.hadoop.hbase.exceptions.UnknownProtocolException: No registered 
coprocessor service found for name CubeVisitService in region 
KYLIN_GA464RXYQX,,1484635706236.9aac092cc3bd8855999c7a8734f09842.

how can I resolve this problem?
