> STR:

> 2) After cluster will be deployed, change cluster name
> 3) try to upgrade ambari to 2.4.0 version
> During upgrade you will get this issue:
> {code}
> Error output from schema upgrade command:

> In general this method "upgradeCapSchedulerView" was added to upgrade CUSTOM capacity scheduler view to Remote but "if" construction is not complete. Because when we are doing cluster name update, {{cluster_handle}} column will not be updated correctly(for ambari 2.2.2). So later during upgrade when you changing {{cluster_name}} from string to int(cluster id) nothing will be set in this column.
