Statistics (records read by each mapper and reducer)
Key: PIG-626
URL: https://issues.apache.org/jira/browse/PIG-626
Project: Pig
Issue Type: New Feature
Components: impl
Affects Versions: 0.2.0
Reporter: Shubham Chopra
Assignee: Shubham Chopra
Priority: Minor
Fix For: 0.3.0
Attachments: PIG-626.patch, pigStats.patch, pigStats.patch,

TEST-org.apache.pig.test.TestBZip.txt
This uses the counters framework that hadoop has. Initially, I am just
interested in finding out the number of records read by each mapper/reducer
particularly for the last job in any script. A sample code to access the
statistics for the last job:
String reducePlan =
stats.getPigStats().get(stats.getLastJobID()).get(PIG_STATS_REDUCE_PLAN);
if(reducePlan == null) {
System.out.println(Records written : +
stats.getPigStats().get(stats.getLastJobID()).get(PIG_STATS_MAP_OUTPUT_RECORDS));
} else {
System.out.println(Records written : +
stats.getPigStats().get(stats.getLastJobID()).get(PIG_STATS_REDUCE_OUTPUT_RECORDS));
}
The patch contains 7 test cases. These include tests PigStorage and
BinStorage along with one for multiple MR jobs case.

1. The initial goal is to just get the pig query result sizes. I try to get the
no. of records written by the last job which gives me the required metric. In
addition to this I am making the stats for all the jobs available. I am not
adding any specific stat to map/reduce.
2. I am only using the hadoop counters here. I am not registering any
pig-specific counters. Olga had suggested that I make the counters available in
the form of a map with the keys starting with PIG_STATS to reference the
required counter.
Hadoop has a bunch of counters that it uses to display stats in its map-red
webUI. These counters give the no. of records and bytes read/written by
map/reduce of each job. I am making all the hadoop stats, at the granularity of
a record, available.
3. I have rectified this in the new patch.
4. These counters are incremented within hadoop.
