What should be the default number of threads here? If a HRS holds 100 of regions - will 10 threads be enough? This issue will try to resolve this with tests and discussions and suitable patch will be updated in HBASE-14970 for branch-1 once this is committed. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
