原文链接： https://blog.csdn.net/shfshihuafeng/article/details/90734595

一. Region在Meta信息完整，Regioninfo文件丢失
   1.异常定位
       全局检查

      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检查

        hbck  -details检查，如果没有Unable to read .tableinfo from " + hbaseRoot + "/" + tableName异常

        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.确认异常信息  
确定031355e76d2c8550196eb3284b25a4a6的meta信息

检查meta表 Meta确定缺失031355e76d2c8550196eb3284b25a4a6在meta是否存在

scan 'hbase:meta', FILTER=>"RowFilter(=,'substring:031355e76d2c8550196eb3284b25a4a6')"

Region的Meta信息完好，可以断定hole是由regioninfo文件丢失导致。

 

在页面确定Rs信息

这种就是只有regioninfo丢失

3. 修复
Assign region

assign  '031355e76d2c8550196eb3284b25a4a6'

确认有问题regioninfo  '031355e76d2c8550196eb3284b25a4a6'

 ./hbase wck -source default:testorphan1 -option checkTable

4. 检查
 Hbck -details
