Hi Joel, Kylin calculates the split keys during cube building; once a segment be built, it (and the htable) is immutable (no data be inserted/deleted), so there is no need to rebalance;
>From 1.5.2, the "kylin.hbase.region.cut" determins the size of a region; But as Kylin calculates the split keys by estimation; the real size of a region may vary a little; The link in the code is out of date and mis-leading, will remove that soon; 2016-06-09 14:36 GMT+08:00 Joel Victor <[email protected]>: > Hi, > > Can some one please explain why region splitting for HBase has been > disabled?
