Subject [jira] [Created] (PHOENIX-3139) phoenix-hive assembly target overwrites input jar

---------------------------------------

             Summary: phoenix-hive assembly target overwrites input jar
                 Key: PHOENIX-3139
                 URL: https://issues.apache.org/jira/browse/PHOENIX-3139
             Project: Phoenix
          Issue Type: Bug
    Affects Versions: 4.8.0
            Reporter: Andrew Purtell


There is a maven-assembly-plugin target in the phoenix-hive module POM not present in other
extension module POMs like for phoenix-pig or phoenix-flume.

This assembly target creates a jar-with-dependencies assembly as phoenix-hive/target/phoenix-<version>-hive.jar.
I think that path is also an implicit input to the assembly as the output of the earlier compile
phase. I say that because I see the build failing with an odd error:

{noformat}
[ERROR] Failed to execute goal org.apache.maven.plugins:maven-assembly-plugin:2.5.2:single
(make-jar-with-dependencies) on project phoenix-hive:
Failed to create assembly:
Error creating assembly archive jar-with-dependencies:
Problem creating jar:
jar:file:/.../phoenix-hive/target/phoenix-hive-<version>.jar!/org/apache/phoenix/hive/mapreduce/PhoenixRecordWriter.class:
JAR entry org/apache/phoenix/hive/mapreduce/PhoenixRecordWriter.class not found in /.../phoenix-hive/target/phoenix-hive-<version>.jar
-
{noformat}

Makes sense that the archiver can't find a class file in a jar if a writer is racing with
a reader on the same file.

What was the intent here? Commenting out the maven-assembly-plugin instructions in the phoenix-hive
POM fixes (or at least avoids) this problem.
