hi,I've fixed this bug in my native code like this, and it works well. Is there
anything wrong with this? !image-2018-01-16-11-48-18-812.png!
{code:java}
//class org.apache.kylin.rest.service.CubeService
private void mergeCubeSegment(String cubeName) {
CubeInstance cube = getCubeManager().getCube(cubeName);
if (!cube.needAutoMerge())
return;
synchronized (CubeService.class) {
try {
cube = getCubeManager().getCube(cubeName);
SegmentRange offsets = cube.autoMergeCubeSegments();
if (offsets != null) {
//fix auto merge fail
// CubeSegment newSeg = getCubeManager().mergeSegments(cube,
null, offsets, true);
TSRange tsRange = new TSRange((Long)offsets.start.v,
(Long)offsets.end.v);
CubeSegment newSeg = getCubeManager().mergeSegments(cube,
tsRange, null, true);
logger.debug("Will submit merge job on " + newSeg);
DefaultChainedExecutable job =
EngineFactory.createBatchMergeJob(newSeg, "SYSTEM");
