ramkrishna.s.vasudevan updated HBASE-18002: ------------------------------------------- Status: Patch Available (was: Open) > Investigate why bucket cache filling up in file mode in an exisitng file is > slower > ----------------------------------------------------------------------------------- > > 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 > Assignee: ramkrishna.s.vasudevan > Fix For: 2.0.0 > > Attachments: HBASE-18002_1.patch, HBASE-18002.patch > > > 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. -- This message was sent by Atlassian JIRA (v6.4.14#64029)
