Description

On execution of wal_roll command in shell, error message gets displayed as shown below

hbase(main):005:0> wal_roll 'host-10-19-92-94,16201,1424081618286'

ERROR: cannot convert instance of class org.jruby.RubyString to class org.apache.hadoop.hbase.ServerName

its because Admin Java api expecting a ServerName object but script passes the ServerName as string.
currently script is as below

@admin.rollWALWriter(server_name)

It should be like

@admin.rollWALWriter(ServerName.valueOf(server_name))
