I was trying to scan the META table of a hbase instance.. And it is unable to..
On further inspection, the region server that hosts the meta tableis filled
with exceptions like the following in its logs:
2010-08-24 23:30:58,412 ERROR

Can you guys let me know if this is a known bug? The offset seems dubiously
high..
