Subject Problem I'm having with Release Candidate 0.1.2
Date Tue, 29 Apr 2008 02:04:48 GMT
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).
