How can I drop my table
There is a file CORRUPT in HDFS then hbase can't handle client's request
well.
I want to truncate it but there is a NativeException raised.
How can I handle this problem?
Thanks.

Re: How can I drop my table
Posted by Stack <st...@duboce.net>.
Do you only have one replica for those blocks?
Can you pull those files down local or do you get the corrupt message?
./bin/hadoop fs -get FILENAME /tmp/
You could also remove those files and then reopen the regions hosting
those files.
./bin/hadoop fs -rm FILENAME
... then
./bin/hadoop fs -cat /hbase/FRPD_LCRECIPETECH/990451997/.regioninfo
... to get the region name. Then in hbase shell
hbase> close_region REGIONNAME
To drop table, disable it and then drop it:
hbase> disable TABLENAME
hbase> drop TABLENAME
The above can be flakey and make take a few attempts.
