hi, when i use kylin 2.3.1 build huge cube, got error at 'Extract Fact Table Distinct Columns', reduce job fail because of Java heap space, i suspect the num of reducer is too less, so tried many parameter to increase reducer, but is not working, see my parameter as below:
kylin.engine.mr.mapper-input-rows 200000 kylin.engine.mr.min-reducer-number 26 kylin.storage.hbase.hfile-size-gb 0.5 kylin.storage.hbase.min-region-count 28 kylin.storage.hbase.region-cut-gb 0.5 kylin.query.max-return-rows 7000000 kylin.engine.mr.uhc-reducer-count 30 kylin.storage.hbase.max-region-count 500 is any suggestion for this? thanks chenxingyu
