Critical Description
On the "Writing Clients" doc page, in the section "SCANNER" (at http://accumulo.apache.org/1.4/user_manual/Writing_Accumulo_Clients.html#Reading_Data), there is the following code snippet:
for(Entry<Key,Value> entry : scan) { String row = e.getKey().getRow(); Value value = e.getValue(); }
In the loop body, e should be entry.
The same error also exists further down the page in the "BATCHSCANNER" section.
