ramkrishna.s.vasudevan commented on HBASE-18002:
------------------------------------------------
I think for actual persistance to happen we need to configure
'BUCKET_CACHE_PERSISTENT_PATH_KEY' this also right? If we don't do that then
the meta data of the persistance is not available so nothing will be retrieved
back? I have not checked the code fully. Just got that param from github link.
Will work on this next week.

> Key: HBASE-18002
> URL: https://issues.apache.org/jira/browse/HBASE-18002
> Project: HBase
> Issue Type: Sub-task
> Components: BucketCache
> Affects Versions: 2.0.0
> Reporter: ramkrishna.s.vasudevan
> Fix For: 2.0.0

>
> This issue was observed when we recently did some tests with SSD based bucket
> cache. Similar thing was also reported by @stack and [~danielpol] while doing
> some of these bucket cache related testing.
> When we try to preload a bucket cache (in file mode) with a new file the
> bucket cache fills up quite faster and there not much 'failedBlockAdditions'.
> But when the same bucket cache is filled up with a preexisitng file ( that
> had already some entries filled up) this time it has more
> 'failedBlockAdditions' and the cache does not fill up faster. Investigate why
> this happens.
