-----------------------------------
Summary: Balancer tend to move regions to the server at the end of
list
Key: HBASE-26309
URL: https://issues.apache.org/jira/browse/HBASE-26309
Project: HBase
Issue Type: Bug
Components: Balancer
Reporter: Clara Xiong
When we have a cohosted regions, cohosted replica distribution has priority to
region count skew. So we won't see region count getting balanced until the
replicas distributed. During this time, master UI shows a drift of regions to
the server at the end of list and causes significant overload. This shows a
bias of random region pick and needs to be addressed.
