The following rows are copied from the default Kylin configuration file: # HBase min and max region count kylin.hbase.region.count.min=1 kylin.hbase.region.count.min=500 I guess the 500 should be max? When I built my first cube, I did not change anything in the configuration file which means we set the minimum region count twice. And the following is one of the HTable I got: HTable: KYLIN_O03ZWB4DK9 * Region Count: 979 * Size: 5.75 TB * Start Time: 2011-12-31 00:00:00 * End Time: 2014-05-01 01:00:00 The region count is 979 which is definitely larger than 500. Does it mean that the setting actually did not work? Best regards, Zhong -- Best regards, Shaofeng Shi
