Hi! We have a strange situation with Kylin performance. Sometimes queries to Kylin last hundreds and thousands seconds. Considering that our web portal runs several of these queries when user uses portal this performance issue leads to the situation when web portal stops working at all. Sometimes the same queries last several seconds (without using Kylin cache). We can't find any relations to HDFS or HBase performance. Are there any best practices to debug this situation and find the bottleneck? We don't understand if Kylin or HBase is the reason. By now we discovered that our biggest cube has 500 regions in HBase. We have default kylin.hbase.region.cut parameter and Kylin 2.1 version. I guess it's not normal situation to have hundrets of regions.
