iterator priority conflict in README.combiner
Here is the relevant section of README.combiner:
$ bin/accumulo shell -u username
Enter current password for 'username'@'instance': ***
Shell - Accumulo Interactive Shell
-
- version: 1.5.x-incubating
- instance name: instance
- instance id: 00000000-0000-0000-0000-000000000000
-
- type 'help' for a list of available commands
-
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:
05 12:24:15,852 [shell.Shell] ERROR:
java.lang.IllegalArgumentException: iterator priority conflict:
table.iterator.majc.decStats=10,org.apache.accumulo.examples.combiner.StatsCombiner
My interpretation is that the -p parameter can't be the same for both
setiter commands. If anyone confirms this, I'll make a JIRA ticket.

Yes, that's correct.
