Subject Re: some region Could not seek StoreFileScanner[HFileScanner for reader

Yongjiang,

If it is not too late (in any case this may help others):

Try to check cluster with hbck tool (http://hbase.apache.org/book.html#hbck),
use -details flag to see the errors. If there are, try to fix them with
"-fix" option.

I saw same error [1] as you are describing and this helped me.

Same error in log as you have when trying to access the region.

hbck showed:

ERROR: Region agg-sa-1.3,0011|
qb|5mhb|\x00\x00\x00\x00\x00C\xA3\x98\x004\x00\x00\x00\x015\xA0\x83K\xC4\x00\x00\x00\x00\x00\x00\x00\x00,1330889041182.a1177c1159592a1e87b49c607e49edc0.
is listed in META on region server xxx.ec2.internal:60020 but is multiply
assigned to region servers xxx.ec2.internal:60020, xxx.ec2.internal:60020
