Duo Zhang commented on HBASE-18031:
-----------------------------------
As the reopening of StoreFileScanner has to take care of the reference of
HFileBlock in L2 cache, it is much more complicated to do a background
switching. I do not think it can be resolved soon so move it out and link it
with the old parent issue.
> Reopen StoreFileScanners in background when switching from pread to stream
