Shanmukha Haripriya Kota updated HBASE-27752:
---------------------------------------------
Description: Currently, we maintain a list of Hfiles on disk for which
prefetch is complete and avoid prefetching those files after a restart. But we
don't handle cases where blocks are evicted from the cache. This ticket is for
updating the list of prefetched files when the region is moved but the blocks
from that region are not evicted. (was: Currently, we maintain a list of
