HBase长时间无法关闭[Waiting on regionserver(s) to go down]
为了释放已经删除的region,重启hbase,执行./bin/stop-hbase.sh。
等了很久还未关闭,查看master日志,显示一直在等待regionserver
2015-07-08 09:11:25,800 INFO org.apache.hadoop.hbase.master.ServerManager: Waiting on regionserver(s) to go down Colander-hb01,60020,1435801056660
再去查看此regionserver情况,日志显示Region is not online
2015-07-08 09:17:34,419 DEBUG org.apache.hadoop.hbase.regionserver.HRegionServer: NotServingRegionException; Region is not online: COLANDER_DownloadedURL,com.soku.www:http/t/nisearch/Camino+sangriento+6/_cid_15_time_100_sort_score_display_album_high_24?sfilter=1,1417099858158.e9e95f20d0f45860aa0778a5b6e97dbc.
陷入了死循环的情况,永远也无法完成关闭。
尝试手动强制关闭regionserver,成功了
./bin/hbase-daemons.sh stop regionserver
随即,hbase成功关闭。
