[jira] [Created] (CASSANDRA-14795) Expose information about stored
hints via JMX
Aleksandr Sorokoumov created CASSANDRA-14795:
------------------------------------------------
Summary: Expose information about stored hints via JMX
Key: CASSANDRA-14795
URL: https://issues.apache.org/jira/browse/CASSANDRA-14795
Project: Cassandra
Issue Type: Improvement
Reporter: Aleksandr Sorokoumov
Assignee: Aleksandr Sorokoumov
Currently there is no way to determine what kind of hints a node has, apart from looking at the filenames (thus host-ids) on disk. Having a way to access this information would help with debugging hint creation/replay scenarios.
In addition to the JMX method, there is a new nodetool command:
{noformat}$ bin/nodetool -h 127.0.0.1 -p 7100 listendpointspendinghints
