----------------------------------
Summary: Query got IllegalArgumentException
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

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.
