[jira] [Updated] (CASSANDRA-15324) Unable to compute ceiling for
max when histogram
[ https://issues.apache.org/jira/browse/CASSANDRA-15324?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Hsu miau luan updated CASSANDRA-15324:
--------------------------------------
Description:
I have 9 cassandra nodes. When I create a keyspace that has 15 tables and the record count of all table are about 8.2 billion. I imported data through my java loaders, and I found out the system.log has error message. What happened and how can I solve the error?
