The alarm is generated when the heap memory usage of a JobHistory2x Process exceeds the threshold (95% of the maximum memory). In MRS 3.3.0-LTS and later versions, the Spark2x component is renamed Spark, and the role names in the component are also changed. For example, JobHistory2x is...

The system checks the heap memory usage of the Flume service every 60 seconds. This alarm is generated when the heap memory usage of the Flume instance exceeds the thresh
The cluster consists of 22 nodes, and 20 of them are data nodes, each node has 16GB as the heap memory. The thing is, when I'm doing massive queries, some of the nodes(2 or 3) consume 70% of the heap memory, while the rest just use less than 10%. So I'm wondering is this ...
This project is about the study of heap memory consumption of thread-safe containers for its write operations. This project compares the heap memory usage of both synchronized and concurrent containers of Java. A systematic method of performance analysis is opted. The system takes the workload ...
——On Heap vs Off Heap Memory Usage - DZone Performance I was recently asked about the benefits and wisdom of using off heap memory in Java. The answers may be of interest to others facing the same choices. Off heap memory is nothing special. The thread stacks, application code, NIO bu...

2、The memory usage of the driver when submitting through Spark SQL is as follows: From the comparison, we can see that the JVM memory usage of the Kyuubi Spark engine driver differs significantly in the areas of Class, Thread, GC, and Internal. The off-heap memory usage of the driver ...
This disclosure provides a computing system and method to profile a program for finding potential optimization in heap usage by reducing lag and drag in lifetimes of heap memory blocks. The process consists of three steps. First, an instrumentation engine analyzes a given program, and inserts addit...
