> First ,disable a real time streaming cube when the cube has max building jobs (default max  job size is 10),then enable the cube。But this cube may can't subbmit new building jobs any more even if the kylin user have discarded the building jobs ,it logs "No left quota to build segments for cube". Because the amount of left quota one cube can submit building jobs is determined by this algorithm: allowMaxBuildingSegments - inBuildingSegments". The 'allowMaxBuildingSegments' is configed and the 'inBuildingSegments ' are the cube's not ready segments in hbase(perhaps some other storage).
