She*_*eng 18 hadoop hbase opentsdb
我设置了一个hbase集群来存储来自opentsdb的数据.最近由于重启了一些节点,hbase丢失了表"tsdb".我仍然可以在hbase的主节点页面上,但是当我点击它时,它给了我一个tableNotFoundException
org.apache.hadoop.hbase.TableNotFoundException: tsdb

我进入了hbase shell,尝试找到'tsdb'表,但得到了类似的消息
hbase(main):018:0> scan 'tsdb'
ROW COLUMN+CELL
ERROR: Unknown table tsdb!

但是当我试图重新创建这个表时,hbase shell告诉我该表已经存在...
hbase(main):013:0> create 'tsdb', {NAME => 't', VERSIONS => 1, BLOOMFILTER=>'ROW'}
ERROR: Table already exists: tsdb!

我还可以在hbase shell中列出该表
hbase(main):001:0> list

看一下日志,我发现这应该是我的问题的原因

它说在.META中找不到tsbb行,但在.META中确实存在tsdb行.

这是我在集群上运行"hbck"后的结果

遗憾的是,这并没有解决我的问题
有人可以帮我解决这个问题

非常感谢!
有点晚了,也许对搜索者有帮助.
hbase zkclils /hbase/tablermr /hbase/table/TABLE_NAME我不太清楚为什么你无法扫描它。但是,要重新创建表,您可以尝试以下操作:
1)手动删除该表的.META表中的所有条目,并且
2)从HDFS中删除该表对应的目录
之后尝试再次创建该表。
