Re: 答复: Re: Timeout visiting cube!

Hi Gaolv, Did you compare the difference of the HTable before and after running " org.apache.kylin.storage.hbase.util.DeployCoprocessorCLI"? You can build a new segment, and then describe the table in hbase shell; and then run the DeployCoprocessorCLI, then describe it again to see whether there
