Re: Problem I'm having with Release Candidate 0.1.2

[stack]

I just tried it w/ a decent sized table and ran into the same issue.  
For a while we've known offlining to be unreliable, HBASE-478, and 
intended fixing it for 0.2.0 but with this demonstration of how bad our 
offlining is currently working, I think it needs to be fixed in the 
branch and included in 0.1.2 release.  I'll put up a new candidate in a 
few days.

Did your upload work?

New piece of info. Now a simple select count(*) from sample_table; results
in the following error:

HRegionInfo was null or empty in .META.

Ever since upgrading to the first 0.1.2 release candidate, I cannot alter
or drop a table. The shell reports the operation succeeded, but the master
node starts failing to respond to any requests (although it's still
running). Stopping and starting hbase causes the table to be unchanged.
Below is a DEBUG output from an attempt to drop a table (you'll note no
interesting messages).
