Hudson commented on HBASE-15515: -------------------------------- SUCCESS: Integrated in HBase-1.3-IT #580 (See [https://builds.apache.org/job/HBase-1.3-IT/580/]) HBASE-15515 Improve LocalityBasedCandidateGenerator in Balancer (tedyu: rev ff261efbf7ff8f4947dcb9387720b611acc86e71) * hbase-server/src/main/java/org/apache/hadoop/hbase/master/balancer/RegionLocationFinder.java * hbase-server/src/main/java/org/apache/hadoop/hbase/master/balancer/BaseLoadBalancer.java * hbase-server/src/main/java/org/apache/hadoop/hbase/master/balancer/StochasticLoadBalancer.java > Improve LocalityBasedCandidateGenerator in Balancer > --------------------------------------------------- > > Key: HBASE-15515 > URL: https://issues.apache.org/jira/browse/HBASE-15515 > Project: HBase > Issue Type: Bug > Affects Versions: 2.0.0, 1.3.0 > Reporter: Guanghao Zhang > Assignee: Guanghao Zhang > Priority: Minor > Fix For: 2.0.0, 1.3.0, 1.4.0 > > Attachments: HBASE-15515-v1.patch, HBASE-15515.patch > > > There are some problems which need to fix. > 1. LocalityBasedCandidateGenerator.getLowestLocalityRegionOnServer should > skip empty region. > 2. When use LocalityBasedCandidateGenerator to generate Cluster.Action, it > should add random operation instead of pickLowestLocalityServer(cluster). > Because the search function may stuck here if it always generate the same > Cluster.Action. > 3. getLeastLoadedTopServerForRegion should get least loaded server which have > better locality than current server. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
