The JIRA is to create a utility which restarts a single region server by: > 1. blacklisting the region server > 2. moving all the regions one by one > 3. restart the region server process > 4. moving all the regions back > 5. removing the region server from blacklist > Along with this, the utility should also be able to estimate the total outage observed from client perspective. -- This message is automatically generated by JIRA.
