---------------------------------
Summary: Hack around Hadoop2's job counter limits
Key: CRUNCH-292
URL: https://issues.apache.org/jira/browse/CRUNCH-292
Project: Crunch
Issue Type: Bug
Components: Core
Affects Versions: 0.7.0
Reporter: Josh Wills
Assignee: Josh Wills
Hadoop2 introduces limits in the Counters library that set a maximum of 120
counters per job. These limits are really hard to hack around (for some good
reasons); the only real way to override them is to update mapred-site.xml and
restart the cluster.
This presents a challenge for Crunch's in-memory implementation, which uses the
Counters library in local mode and can potentially generate well more than 120
counters when testing long pipelines.
