Dmitriy V. Ryaboy updated PIG-1427: ----------------------------------- Status: Resolved (was: Patch Available) Fix Version/s: 0.8.0 Resolution: Fixed Committed. > Monitor and kill runaway UDFs > ----------------------------- > > Key: PIG-1427 > URL: https://issues.apache.org/jira/browse/PIG-1427 > Project: Pig > Issue Type: New Feature > Affects Versions: 0.8.0 > Reporter: Dmitriy V. Ryaboy > Assignee: Dmitriy V. Ryaboy > Fix For: 0.8.0 > > Attachments: guava-r03.jar, monitoredUdf.patch, monitoredUdf.patch, > PIG-1427.diff, PIG-1427.diff, PIG-1427.diff > > > As a safety measure, it is sometimes useful to monitor UDFs as they execute. > It is often preferable to return null or some other default value instead of > timing out a runaway evaluation and killing a job. We have in the past seen > complex regular expressions lead to job failures due to just half a dozen > (out of millions) particularly obnoxious strings. > It would be great to give Pig users a lightweight way of enabling UDF > monitoring. -- This message is automatically generated by JIRA. - You can reply to this email to add a comment to the issue online.
