Cheolsoo Park commented on PIG-3905:
------------------------------------
I think this is a valid bug. Even though the build doesn't fail for me (because
hadoop-core-1.0.0.jar is found in maven repo), hadoop20 and hadoop23 confs are
always resolved regardless hadoopversion-
{code}
[ivy:resolve] :: resolving dependencies :: org.apache.pig#pig;0.12.2-SNAPSHOT
[ivy:resolve] confs: [master, default, runtime, compile, test, javadoc,
releaseaudit, jdiff, checkstyle, buildJar, hadoop20, hadoop23, hbase94, hbase95]
{code}
This seems wrong to me.
For example, sqoop only resolves one hadoop conf specified by hadoopversion-
{code}
[ivy:resolve] :: resolving dependencies ::
com.cloudera.sqoop#sqoop;working@lgml-cheolsoop
[ivy:resolve] confs: [hadoop20]
{code}
We should fix this. I don't have an explanation why this becomes an issue in
0.12.1 because it has existed since the beginning.

> URL: https://issues.apache.org/jira/browse/PIG-3905
> Project: Pig
> Issue Type: Bug
> Components: build
> Affects Versions: 0.12.1
> Reporter: Konstantin Boudnik
> Priority: Blocker
>
> While building Pig against {{hadoopversion=23}}, attempts to resolve
> {{hadoop-core}} dependency no matter what. The root cause of the bug is the
> following lines in ivy.xml
> {noformat}
> <dependency org="com.sun.jersey" name="jersey-core"
> rev="${jersey-core.version}"
> conf="hadoop20->default"/>
> <dependency org="org.apache.hadoop" name="hadoop-core"
> rev="${hadoop-core.version}"
> conf="hadoop20->default"/>
> <dependency org="org.apache.hadoop" name="hadoop-test"
> rev="${hadoop-test.version}"
> conf="hadoop20->default"/>
> {noformat}
> hadoop20 configuration is getting evaluated _always_. Unless a build machine
> has dirty local .m2 repository, the build will fail.
> The bug blocks BIGTOP-1110
