Problem scenario
When you start Cassandra you see a message such as this:
INFO [main] 2018-02-03 08:45:55,257 ColumnFamilyStore.java:389 - Initializing system.IndexInfo
What should you do?
Possible Solution #1
Try rebooting the server. This could help the problem.
Possible Solution #2
This next one is merely a workaround. It is not a best practice.
Edit the ColumnFamilyStore.java file. To find it use this:sudo find / -name ColumnFamilyStore.java
Comment out line 389. It should look like this after you comment it out: //logger.info("Initializing {}.{}", keyspace.getName(), name);
Start Cassandra again. But know that you modified the source code without a though quality assurance process. This could have serious ramifications in the future.
Possible Solution #3
Wait 60 minutes. If you are patient enough, it is possible that the problem will go away on its own.
Possible Solution #4
Verify you have sufficient hardware for your version of Cassandra. Reinstall Cassandra; if you need assistance, click on the link for your distribution of Linux:
