Ahmed Guecioueur created CASSANDRA-5253:
-------------------------------------------
Summary: NPE while loading Saved KeyCache
Key: CASSANDRA-5253
URL: https://issues.apache.org/jira/browse/CASSANDRA-5253
Project: Cassandra
Issue Type: Bug
Components: Core
Affects Versions: 1.2.1
Environment: JVM vendor/version: Java HotSpot(TM) Client VM/1.7.0_11
OS: Windows 7 Enterprise SP1, x64.
Reporter: Ahmed Guecioueur
Priority: Minor
This bug occurred in the Beta version and was marked as fixed in this Jira:
CASSANDRA-4553
However it seems to have reoccurred in the production 1.2.1 release. This is
the first install I have made of Cassandra (so a clean install), which I
downloaded prepackaged from
http://www.apache.org/dyn/closer.cgi?path=/cassandra/1.2.1/apache-cassandra-1.2.1-bin.tar.gz
I have created a keyspace but not inserted any data, so that is not the issue
either.
Here is a sample from the logs all the way from startup
