Subject java.lang.IllegalAccessError while opening region
Date Mon, 10 May 2010 20:35:49 GMT
Hi All,

I have reams of errors in my master log for a single region.  It keeps
trying and failing to open the region. An example of the exception is below.
 Are there conceivable ways of fixing this or am I most likely going to have
to delete the region.  If deleting the region is the likely option, are
there any tools to help with this?  I saw the recent message from Stack
describing how to delete a region. Does that mean I have to manually edit
.META. from the hbase shell?  Do I also have to edit the .regioninfo files
in the modified regions' directories with the new start/end keys?

Thanks!
