                 Key: KYLIN-3059
                 URL: https://issues.apache.org/jira/browse/KYLIN-3059
             Project: Kylin
          Issue Type: Bug
          Components: Query Engine
    Affects Versions: v1.6.0
         Environment: apache-kylin-1.6.0-hbase1.x
apache hadoop 2.7.2
hbase-1.2.4
            Reporter: Xingxing Di
            Assignee: liyang
             Fix For: all
         Attachments: query.log

A query got an exception , the error trace was :

Caused by: java.lang.IllegalArgumentException
        at com.google.common.base.Preconditions.checkArgument(Preconditions.java:76)
        at org.apache.kylin.metadata.model.TblColRef.<init>(TblColRef.java:105)
        at org.apache.kylin.metadata.model.TblColRef.columnForUnknownModel(TblColRef.java:74)
        at org.apache.kylin.query.relnode.OLAPTableScan.buildColumnRowType(OLAPTableScan.java:231)

the code is : 
    TblColRef(TableRef table, ColumnDesc column) {
        checkArgument(table.getTableDesc() == column.getTable()); // this line cause exception
        this.table = table;
        this.column = column;
    } 

and after we did "Reload metadata", query executed successful.

I dont know what will cause this exception,  i think it may related to ProjectL2Cache or ProjectManager.
