一. Region在Meta信息完整，Regioninfo文件丟失
1.異常定位
全局檢查
hbck -details testorphan1
ERROR: Orphan region in HDFS: Unable to load .regioninfo from table testorphan1 in hdfs dir hdfs://hadoop01:9000/hbase/data/default/testorphan1/031355e76d2c8550196eb3284b25a4a6! It may be an invalid format or version file. Treating as an orphaned regiondir.
19/06/05 14:42:56 WARN util.HBaseFsck: Failed to read .regioninfo file for region testorphan1,100,1559716712083.031355e76d2c8550196eb3284b25a4a6.
HDFS檢查
hbck -details檢查，如果沒有Unable to read .tableinfo from " + hbaseRoot + "/" + tableName異常
hbase hbck -fixTableOrphans "testorphan1"
ERROR: Orphan region in HDFS: Unable to load .regioninfo from table testorphan1 in hdfs dir hdfs://hadoop01:9000/hbase/data/default/testorphan1/031355e76d2c8550196eb3284b25a4a6! It may be an invalid format or version file. Treating as an orphaned regiondir.
19/06/05 14:45:12 WARN util.HBaseFsck: Failed to read .regioninfo file for region null
java.io.FileNotFoundException: File does not exist: /hbase/data/default/testorphan1/031355e76d2c8550196eb3284b25a4a6/.regioninfo
ERROR: There is a hole in the region chain between 100 and 200. You need to create a new .regioninfo and region dir in hdfs to plug the hole.
2.確認異常信息
確定031355e76d2c8550196eb3284b25a4a6的meta信息
檢查meta表 Meta確定缺失031355e76d2c8550196eb3284b25a4a6在meta是否存在
scan 'hbase:meta', FILTER=>"RowFilter(=,'substring:031355e76d2c8550196eb3284b25a4a6')"
Region的Meta信息完好，可以斷定hole是由regioninfo文件丟失導致。
在頁面確定Rs信息
這種就是隻有regioninfo丟失
3. 修復
Assign region
assign '031355e76d2c8550196eb3284b25a4a6'
確認有問題regioninfo '031355e76d2c8550196eb3284b25a4a6'
./hbase wck -source default:testorphan1 -option checkTable
4. 檢查
Hbck -details
