Key: HBASE-5307
URL: https://issues.apache.org/jira/browse/HBASE-5307
Project: HBase
Issue Type: Bug
Components: scripts
Affects Versions: 0.92.0
Reporter: YiFeng Jiang
Unable to gracefully decommission a node because NameError occurred in
region_mover.rb
{code}
$ bin/graceful_stop.sh ip-10-160-226-84.us-west-1.compute.internal
...
NameError: no constructorfor arguments (org.jruby.RubyString) on
Java::OrgApacheHadoopHbase::HServerAddress
available overloads:
(org.apache.hadoop.hbase.HServerAddress)
(java.net.InetSocketAddress)
getRegions at /usr/local/hbase/current/bin/region_mover.rb:254
unloadRegions at /usr/local/hbase/current/bin/region_mover.rb:314
(root) at /usr/local/hbase/current/bin/region_mover.rb:430
Unloaded ip-10-160-226-84.us-west-1.compute.internal region(s)
ip-10-160-226-84.us-west-1.compute.internal: stopping regionserver..
{code}
The reason is the region_mover.rb calls wrong HBase APIs to try to establish a
connection to the region server.
