Project: Accumulo
Issue Type: Improvement
Components: docs
Reporter: David Medinets
Assignee: Adam Fuchs
Priority: Trivial
Here is the relevant section of README.combiner:
$ bin/accumulo shell -u username
username@instance> createtable runners
username@instance runners> setiter -t runners -p 10 -scan -minc -majc -n
decStats -class org.apache.accumulo.examples.combiner.StatsCombiner
Combiner that keeps track of min, max, sum, and count
----------> set StatsCombiner parameter columns, <col fam>[:<col
qual>]{,<col fam>[:<col qual>]} escape non aplhanum chars using %<hex>.: stat
----------> set StatsCombiner parameter radix, radix/base of the numbers: 10
username@instance runners> setiter -t runners -p 10 -scan -minc -majc -n
hexStats -class org.apache.accumulo.examples.combiner.StatsCombiner
Combiner that keeps track of min, max, sum, and count
----------> set StatsCombiner parameter columns, <col fam>[:<col
qual>]{,<col fam>[:<col qual>]} escape non aplhanum chars using %<hex>.: hstat
----------> set StatsCombiner parameter radix, radix/base of the numbers: 16
The last command results in an error:

iterator priority conflict:
table.iterator.majc.decStats=10,org.apache.accumulo.examples.combiner.StatsCombiner
Please update the README to change either of the priority parameters.
