Todd Lipcon commented on PIG-200:
---------------------------------
To run in 0.9, I had to make some changes:
- the new signature of bytesToMap in PigPerformanceLoader.Caster has to
delegate to the old implementation (not through UnsupportedOperationException)
- the loader script should really have a "set -e", and ideally figure out which
generation steps have already been completed successfully (mine failed several
hours in due to OOME trying to load a giant lookaside map)
- above Daniel says that you only need to resize "pages" in order to change the
other datasets. But, the script has a variable defined for "widerowcnt" which
implies otherwise. Do we need to manually adjust that or is it ignored? If
ignored it should be set to 0 with a comment explaining that
- cat $powerusers/* will try to cat a _logs directory - should probably only
try to cat the data files

> Key: PIG-200
> URL: https://issues.apache.org/jira/browse/PIG-200
> Project: Pig
> Issue Type: Task
> Reporter: Amir Youssefi
> Assignee: Alan Gates
> Fix For: 0.2.0
>
> Attachments: generate_data.pl, perf-0.6.patch, perf.hadoop.patch,
> perf.patch, pigmix2.patch
>
>
> To benchmark Pig performance, we need to have a TPC-H like Large Data Set
> plus Script Collection. This is used in comparison of different Pig releases,
> Pig vs. other systems (e.g. Pig + Hadoop vs. Hadoop Only).
> Here is Wiki for small tests: http://wiki.apache.org/pig/PigPerformance
> I am currently running long-running Pig scripts over data-sets in the order
> of tens of TBs. Next step is hundreds of TBs.
> We need to have an open large-data set (open source scripts which generate
> data-set) and detailed scripts for important operations such as ORDER,
> AGGREGATION etc.
> We can call those the Pig Workouts: Cardio (short processing), Marathon (long
> running scripts) and Triathlon (Mix).
> I will update this JIRA with more details of current activities soon.
