KYLIN build cube problem

[蒋慧明]

Dear   When I tried to build cube for one day, the report error is different.   Sometimes, the error is : RpcRetryingCaller{globalStartTime=1558076503569, pause=100, retries=1}, java.io.IOException: Call to [HBASE IPXX.XX.XX.XXX:16020]  failed on local exception: org.apache.hadoop.hbase.ipc.CallTimeoutException: Call id=3436827, waitTime=9999, operationTimeout=9998 expired.    Sometimes following error occurs: org.apache.hadoop.hbase.NotServingRegionException: org.apache.hadoop.hbase.NotServingRegionException: Region kylin_metadata is not online on ip-XX.XX.XX.XX,16020,1555901919971    Does anyone know about this problem? Where is the timeout-9998 configured? Why is it not online? Many thanks!
