directly, not sure it make sense or not to keep old htables to have the

You need to check whether the table is existed in hive or not, you can use the

Hi Shrikant,
The log indicated that your query needs data from a snapshot lookup table(your
query columns should contain some derived columns defined in the cube), but the
snapshot is very large, so the query is very slow. You may check the snapshot
size in the lookup table's snapshot tab in K
You may post your query related log here, there should be some query log that
indicated whether the filter is push down or not, at least in the returned
response stats, there's some log show how many rows are filtered in the
coprocessor side.

Could you run jstack on the Kylin process and send out result? So that we can
know what the query threads are blocked on.

The number of reducers in 'fact distinct columns' step is calculated as:

This should be a bug, currently Kylin cannot handle such sub-query
properly(both outside query and sub-query hit cube). The second sql can work is
because there is no subquery exists, and intersect_count is Kylin's udf, you
should define bitmap measure for passenger_id column.

Hi Rahul,
Currently Kylin only store pre-aggregate data, and no raw data is stored in the
system, so Kylin can only support the aggregate query(has group by clause). For
the no-aggregate query, in order to return better results, Kylin just hack to
output sum of metric columns, for example, the q
