--------------------------------------------------------
> Update the list of prefetched Hfiles upon block eviction

> Key: HBASE-27743
> URL: https://issues.apache.org/jira/browse/HBASE-27743
> Project: HBase
> Issue Type: Bug
> Components: BucketCache
> Reporter: Shanmukha Haripriya Kota
> Assignee: Shanmukha Haripriya Kota
> Priority: Major
>
> 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 or when the region is
> moved and the blocks from that region are evicted. The Hfile is kept in the
> prefetch list forever and over time the prefetch list would have all the
> files of the cluster and the prefetch would never be executed. This change
> aims to update the prefetched list of HFiles upon block eviction.
