Key: CASSANDRA-10837
URL: https://issues.apache.org/jira/browse/CASSANDRA-10837
Project: Cassandra
Issue Type: Bug
Reporter: Alex Liu
Assignee: Alex Liu
See a lot of following warnings during Hadoop job running
{code}
ERROR 11:37:45 LEAK: You are creating too many HashedWheelTimer instances.
HashedWheelTimer is a shared resource that must be reused across the JVM,so
that only a few instances are created.
{code}
Each cluster/session needs be closed and a shared HashedWheelTimer may reduce
the resource leakage.
