In the upgrade to DataMiner V10.2.7.0-11922, logs are reporting the below error. There is no reference to this in the release notes, wondering whether there is any impact on the DataMiner due to this error. If there is a manual action that we need to take then do suggest.
|error|Couldn’t remove Cassandra table. Cause: The type initializer for ‘Cassandra.Cluster’ threw an exception..
Hi Srikanth,
This error is caused by the UpgradeAction AnalyticsDropUnusedCassandraTables (see RN 31944, introduced in 10.2.4). This upgrade action removes the following Cassandra tables because they are not actually in use (anymore):
- analytics_arrowwindows_v1
- analytics_patternmatchoccurrences
You could manually remove them by running the following queries:
Drop TABLE sldmadb.analytics_arrowwindows_v1;
Drop TABLE sldmadb.analytics_patternmatchoccurrences;
There’s no harm in leaving the tables since they aren’t used.
