[jira] [Created] (PIG-2299) jetty startup issue causes unit tests
to fail in CI
jetty startup issue causes unit tests to fail in CI
---------------------------------------------------
Key: PIG-2299
URL: https://issues.apache.org/jira/browse/PIG-2299
Project: Pig
Issue Type: Bug
Components: build
Affects Versions: 0.9.1
Environment: RHEL CI server
Reporter: Thomas Weise
We have observed random unit test failures in our pig CI. Same tests working just fine when run on developer machine).
The cause is a bug in jetty version used by pig, example below and more here:
https://issues.apache.org/jira/browse/HADOOP-6386
https://issues.apache.org/jira/browse/HADOOP-6428
https://issues.apache.org/jira/browse/HADOOP-6528
http://jira.codehaus.org/browse/JETTY-748
The issue is resolved by using jetty 6.1.21 instead of 6.1.14

Daniel Dai commented on PIG-2299:
---------------------------------
Newer version(eg:20.204) hadoop fixed this problem. However, since Pig bundles hadoop 20.2, the fix does not goes to Pig. The issue only affects tests. When running on cluster, Pig does not use and will not send jetty to backend.

Daniel Dai commented on PIG-2299:
---------------------------------
Though fix hadoop issue on Pig side doesn't sounds right, but I still think it is better to check in this, reasons are:
1. This block RE folks
2. This change only affects unit test, and all unit tests pass with the patch
3. We don't have plan to upgrade the bundled hadoop version (at least 0.9.1)
Any objection?
