> When using the FileIOEngine for BucketCache, the cache will be disabled if
> the connection is interrupted or closed. HBase will then get
> ClosedChannelExceptions trying to access the file. After 60s, the RS will
> disable the cache. This causes severe read performance degradation for
> workloads that rely on this cache. FileIOEngine never tries to reopen the
> connection. This JIRA is to reopen files when the BucketCache encounters a
> ClosedChannelException.
