Matteo Zuccon updated CASSANDRA-11243: -------------------------------------- Description: Error: "util.ResourceLeakDetector: 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" Using CqlInputFormat.Class as input format for an Hadoop Mapreduce program (on distributed Hadoop Cluster) gives a memory leak error. Version of the library used: <dependency> <groupId>org.apache.cassandra</groupId> <artifactId>cassandra-all</artifactId> <version>3.3</version> </dependency> The same jar is working on a single node Hadoop configuration, the memory leak error show up in the cluster hadoop configuration. was: Error: "util.ResourceLeakDetector: LEAK: You are creating too many HashedWheelTimer instances.
