HBase强制删除一个表,强制删除该表在hdfs上的所有文件(路径根据实际情况而定):

情景:

由于内网测试环境hbase并没有安装“SNAPPY”压缩,而建表时执行了

alter 'TrojanInfo', {NAME => 'i', COMPRESSION => 'SNAPPY'}

强制删除表:

1、强制删除该表在hdfs上的所有文件(路径根据实际情况而定):

./Hadoop fs -rmr /hbase/TrojanInfo

2、删除该表在HBase系统表.META.中的记录:

A、首先从.META.中查询出表 TrojanInfo在.META.中的rowkey,这可以通过scan '.META.',然后手动筛选;

B、然后删除该rowkey下的3个字段(假设查询出的rowkey为TrojanInfo,,1361433390076.2636b5a2b3d3d08f23d2af9582f29bd8.)

delete 'TrojanInfo','TrojanInfo,,1361433390076.2636b5a2b3d3d08f23d2af9582f29bd8.','info:server'

delete 'TrojanInfo','TrojanInfo,,1361433390076.2636b5a2b3d3d08f23d2af9582f29bd8.','info:serverstartcode'

delete 'TrojanInfo','TrojanInfo,,1361433390076.2636b5a2b3d3d08f23d2af9582f29bd8.','info:regioninfo'

C、重启hbase即可删除表 TrojanInfo
