Summary: Rewrap OutOfMemoryError in allocateUnpooledOffHeap with better message Key: FLINK-15989 URL: https://issues.apache.org/jira/browse/FLINK-15989 Project: Flink Issue Type: Improvement Reporter: Andrey Zagrebin Fix For: 1.10.1, 1.11.0 Now if Flink allocates direct memory in MemorySegmentFactory#allocateUnpooledOffHeapMemory and its limit is exceeded for any reason, e.g. user code over-allocated direct memory, ByteBuffer#allocateDirect will throw a generic "OutOfMemoryError: Direct buffer memory". We can catch it and add a message which provides more explanation and points to an option taskmanager.memory.task.off-heap.size to increase as a possible solution. -- This message was sent by Atlassian Jira (v8.3.4#803005)
