Sean Busbey commented on HBASE-20214: ------------------------------------- don't use commons-collections v3. You should use the commons-collection v4 API that's been relocated in the hbase-thirdparty library. FWIW, the description is here: [http://hbase.apache.org/book.html#thirdparty] Basically, any class found in commons-collections4 should be present if you prefix the package with {{org.apache.hbase.thirdparty}}, e.g. {{org.apache.hbase.thirdparty.org.apache.commons.collections4.CollectionUtils}}. > Review of RegionLocationFinder Class > ------------------------------------ > > Key: HBASE-20214 > URL: https://issues.apache.org/jira/browse/HBASE-20214 > Project: HBase > Issue Type: Improvement > Components: Balancer, master > Affects Versions: 2.0.0 > Reporter: BELUGA BEHR > Assignee: BELUGA BEHR > Priority: Minor > Attachments: HBASE-20214.1.patch, HBASE-20214.2.patch > > > # Use SLF4J parameter logging > # Remove superfluous code > # Replace code with re-usable libraries where possible > # Use different data structure > # Small perf improvements > # Fix some checkstyle -- This message was sent by Atlassian JIRA (v7.6.3#76005)
