Summary: BackupHFileCleaner.loadHFileRefs is very expensive Key: HBASE-28538 URL: https://issues.apache.org/jira/browse/HBASE-28538 Project: HBase Issue Type: Bug Components: backup&restore Reporter: Bryan Beaudreault I noticed some odd CPU spikes on the hmasters of one of our clusters. Turns out it had been getting lots of bulkoads (30k) and processing them was expensive. The method scans hbase and then parses the paths. Surprisingly the parsing is more expensive than the reading hbase, with the vast majority of time spent in org/apache/hadoop/fs/Path.<init>. We should see if this is possible to be optimized.
