Jonathan Hsieh created HBASE-6283:
-------------------------------------
Summary: [region_mover.rb] Add option to exclude list of hosts on
unload instead of just assuming the source node.
Key: HBASE-6283
URL: https://issues.apache.org/jira/browse/HBASE-6283
Project: HBase
Issue Type: Improvement
Reporter: Jonathan Hsieh
Currently, the region_mover.rb script excludes a single host, the host
offloading data, as a region move target. This essentially limits the number
of machines that can be shutdown at a time to one. For larger clusters, it is
manageable to have several nodes down at a time and desirable to get this
process done more quickly.
The proposed patch adds an exclude file option, that allows multiple hosts to
be excluded as targets.
