[jira] [Comment Edited] (HIVE-15911) Creating a view based on another view throws an exception “FAILED: NullPointerException null”
[ https://issues.apache.org/jira/browse/HIVE-15911?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15865643#comment-15865643 ]

-----------------------------------------------------------
In the doAuthorization method of the Driver:
if (tbl.isView() && sem instanceof SemanticAnalyzer) {
tab2Cols.put(tbl, sem.getColumnAccessInfo().getTableToColumnAccessMap().get(tbl.getCompleteName()));
}
sem.getColumnAccessInfo returns null, so the code throw exception "NullPointerException null". It needs to call setColumnAccessInfo in the above method.
