----------------------------------------
Summary: MemoryLeak in data load and compaction
Key: CARBONDATA-3787
URL: https://issues.apache.org/jira/browse/CARBONDATA-3787
Project: CarbonData
Issue Type: Bug
Reporter: Ajantha Bhat
Assignee: Kumar Vishal
Direct byte buffer used in #3638, which has memory leak
DirectByteBuffer are cleaned in offheap memory by JVM, when GC happens (when
heap is full). Consider a scenario, where heap is not full, but offheap is
getting full. In this case DirectByteBuffers is not cleaned as GC not happened.
This time we may get OOM from offheap memory and yarn may kill the jvm process.
So, it is better to clean up the DirectByteBuffers after the usage by calling a
reflection method.
