Emilio,
The create table operation is a Fate operation that runs in the Manager. My immediate thought is that maybe the number of Fate operations that you are creating for your other tables is making the create table operation wait for an available thread. I don't have the code in front of me, but I believe there are Fate commands in the shell and via the admin utility that will let you see the status of the Fate operations. If your create operation is sitting there in a submitted state, then it's waiting for a thread. There is a property that you can modify to increase the number of Fate threads. If it's in the running state for a long time, then stacking the Manager to determine where it's spending its time would help us.

Hello,
We've noticed that creating a table in Accumulo 2.1 tends to get slower and slower as the number of tables in the system increases, and once we get have several thousand tables creating more really bogs down (on the order of minutes). Does anyone have any tips on debugging this issue, or known configurations that might help? Or is this not a use case that Accumulo was designed for? I can provide more details on the cluster setup, if it would be helpful.
Thanks,
