> 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.
