-------------------------------------
Summary: [hbck2] Schedule SCP for all unknown servers
Key: HBASE-25587
URL: https://issues.apache.org/jira/browse/HBASE-25587
Project: HBase
Issue Type: New Feature
Components: hbase-operator-tools, hbck2
Reporter: Peter Somogyi
Assignee: Peter Somogyi
Add a command to HBCK2 that schedules SCPs for _unknown servers_. This command
is useful when a new installation of HBase is pointing to a previously used
HBase root directory where the hbase:meta table is populated. This will contain
references to RegionServers from the previous installation and SCP will not be
created against these servers and the regions won't be assigned to the new
server.
The scheduleRecoveries command in HBCK2 could be used to initiate a SCP
one-by-one for the unknown servers, however, collecting the list of servers
could be difficult on a large cluster.
I'm proposing to add a command to HBCK2 that will schedule SCPs for all the
unknown servers in the cluster.
