master fails to start
I searched the archive before posting and didn't find anything. I have a
new system with 12 nodes (3 ZK), and a single user in the hadoop group. The
master fails to start. It looks to me like it is unable to read
/accumulo/instance_id in HDFS, but I can't think why that would be. Thanks
in advance for any advice on how to run this down. Here are the contents of
master.err log:
