> The cause of this bug is not obvious. In the upgrade/downgrade cycle for
> HDP-2.2 upgrade to HDP-2.4 downgrade to HDP-2.2, the Metastore upgrade_schema
> method will invoke configure(). This in turn creates (correctly)
> {{/usr/hdp/current/hive-metastore/conf/conf.server}} to place configs. The
> bug is that upgrade_schema happens BEFORE hdp-select is called, so the
> directory is created within HDP-2.2. Then on downgrade, that directory is
> left intact.
> The alert checks for existence of {{conf/conf.server}} as an indication of
> where to look for configs. Since that directory is incorrect for HDP-2.2,
> the wrong configs are loaded when running the alert script. This is an issue
> when security is enabled since the wrong configs are now checked.
> The fix is to invoke upgrade_schema AFTER hdp-select instead of before. That
> way, the {{conf/conf.server}} directory is created in the correct directory
> in the version that supports it.
