Review comment:
To avoid certain race conditions, it would be nice if we did something
like the following to only resolve the tableName to a tableId once. However I
don't see an easy way to do this.
1. tableId = resolveTableId(tableName)
2. cancelCompaction(tableId)
3. delete(tableId)
Looking around in the code, this would be easy for cancelCompaction because
it already resolves the table id client side. So could create `private
cancelCompaction(TableId)` used by this method and the public
`cancelCompaction(String)` method. However delete table seems like its
currently passing the table name to the server side where it would resolve the
table name to a table id server side. I may have missed it but I tried to
follow the code to the thrift call and did not see anything on the client side
resolving the table id for delete table.
