[Amdatu-developers] [JIRA] (AMDATUCASSANDRA-190) NullPointerException in CassandraStoprageProvider

[Ivo Ladage - van Doorn (JIRA)]

Ivo Ladage - van Doorn edited a comment on AMDATUCASSANDRA-190 NullPointerException in CassandraStoprageProvider There are 4 possible causes of the problem: Invocation of User.getCredentials().remove(key). This removed the property type of the property with the same name as the credential. Invocation of Role.getProperties().put(key, value) with a value that is not a String or a byte[]. In this case the value is inserted into the properties supercolumn, but the corresponsing propertytype is not. Invocation of Role.getCredentials().put(key, value) with a value that is not a String or a byte[]. Same issue as previous one. User properties are retrieved and updated simultaneously from different nodes in the cluster. In this situation it is possible that a value of a property has been inserted and read by another node, but the corresponding property type has not yet been set/synced to this node.
