> Ambari upgrade to Ambari 2.4.0 failed during DB upgrade due to incorrect TEZ
> view regular expression.
> *Steps to Reproduce*
> # Install Ambari 2.2.0
> # Install cluster with TEZ
> # Change {{tez-site/tez.tez-ui.history-url.base}} from something like
> {{http://c6501.ambari.apache.org:8080/#/main/views/TEZ/0.7.0.2.3.4.0-460/TEZ_CLUSTER_INSTANCE}}
> to
> {{http://c6501.ambari.apache.org:8080/#/main/views/TEZ/0.7.0.2.3.4.0-460/tezv1}}
>
> ** Notice "TEZ_CLUSTER_INSTANCE" was changed to "tezv1"
> # Upgrade Ambari to 2.4.0.1
> # Execute {{ambari-server upgrade}}
> # See error

> *Cause*
> The cause for this error is in the regular expression below:
> {code:title=At or around
> org/apache/ambari/server/upgrade/AbstractUpgradeCatalog.java:986}
> String pattern = "(.*\\/TEZ\\/)(.*)(\\/TEZ_CLUSTER_INSTANCE)";
> {code}
> This pattern assumes the URL will end with "TEZ_CLUSTER_INSTANCE", however
> this may be changed by the user causing a failure when matching and yielding
> an exception being thrown.
> *Workaround*
> If the Ambari server package has not yet been upgraded
> # Edit the {{tez-site/tez.tez-ui.history-url.base}} config to match the
> pattern
> # Perform the upgrade
> # Edit the {{tez-site/tez.tez-ui.history-url.base}} config to fix the URL as
> needed
> If the Ambari server package has been upgraded
> # If {{ambari-server upgrade}} has been executed and failed, restore the
> database
> # Using some database access utility (example, Toad), edit the
> {{config_data}} column of the {{clusterconfig}} table for the record that
> represents the _desired_ version of the {{tez-site}} config to match the
> pattern
> # Perform the upgrade
> # Edit the {{tez-site/tez.tez-ui.history-url.base}} config to fix the URL as
> needed
