hongyu bi created HBASE-12957: --------------------------------- Summary: region_mover#isSuccessfulScan may extremely slow on region with lots of expired data Key: HBASE-12957 URL: https://issues.apache.org/jira/browse/HBASE-12957 Project: HBase Issue Type: Improvement Components: scripts Reporter: hongyu bi Priority: Minor
region_mover will call isSuccessfulScan when region has moved to make sure it's healthy, however , if the moved region has lots of expired data region_mover#isSuccessfulScan will take a long time to finish ,that may even exceed "lease timeout".So I made isSuccessfulScan a get-like scan to achieve faster response in that case. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
