When I debug the issue HBASE-22422, I observed that the ByteBuffAllocator#usedBufCount will was always increasing and all direct ByteBuffers would be exhausted, which lead to may heap allocation happen. The comment here [1] is also related to this problem.
Check the code path, the HFileScannerImpl is the biggest suspect, so create issue to address this.
