------------------------------------
Summary: HCatalog documentation example is wrong
Key: HIVE-4590
URL: https://issues.apache.org/jira/browse/HIVE-4590
Project: Hive
Issue Type: Bug
Components: Documentation
Affects Versions: 0.10.0
Reporter: Eugene Koifman
Priority: Minor
http://hive.apache.org/docs/hcat_r0.5.0/inputoutput.html#Read+Example
reads
The following very simple MapReduce program reads data from one table which it
assumes to have an integer in the second column, and counts how many different
values it sees. That is, it does the equivalent of "select col1, count(*) from
$table group by col1;".
The description of the query is wrong. It actually counts how many instances
of each distinct value it find. For example, if values of col1 are
{1,1,1,3,3,3,5) it will produce
1, 3
3, 2,
5, 1
