Reid Chan updated HBASE-23147:
------------------------------
Fix Version/s: (was: 1.7.0)
1.8.0
> Branches-1 shaded artifact for mapreduce integration misses MainClass
> ---------------------------------------------------------------------
>
> Key: HBASE-23147
> URL: https://issues.apache.org/jira/browse/HBASE-23147
> Project: HBase
> Issue Type: Bug
> Components: Client, mapreduce
> Affects Versions: 1.5.0, 1.3.6, 1.4.11
> Reporter: Sean Busbey
> Priority: Major
> Labels: beginner
> Fix For: 1.8.0
>
>
> the shaded artifact we intend for folks to use when doing mapreduce stuff in
> branches-1 is {{hbase-shaded-server}}, but it fails to define the same
> {{MainClass}} for the jar as the {{hbase-server}} artifact. This prevents
> commands like this from working:
> {code}
> $ hadoop jar some/path/to/hbase-shaded-server-1.4.11-SNAPSHOT.jar importtsv
> -Dimporttsv.columns=HBASE_ROW_KEY,family1:column1,family1:column4,family1:column3
> test:example example/ -libjars $(hbase mapredcp)
> Exception in thread "main" java.lang.ClassNotFoundException: importtsv
> at java.net.URLClassLoader.findClass(URLClassLoader.java:381)
> at java.lang.ClassLoader.loadClass(ClassLoader.java:424)
> at java.lang.ClassLoader.loadClass(ClassLoader.java:357)
> at java.lang.Class.forName0(Native Method)
> at java.lang.Class.forName(Class.java:348)
> at org.apache.hadoop.util.RunJar.run(RunJar.java:232)
> at org.apache.hadoop.util.RunJar.main(RunJar.java:153)
> {code}
> The {{hbase-shaded-server}} module pom should have the same maven-jar-plugin
> config for setting the main class as the {{hbase-server}} module.
> This is not an issue in branches-2+ because as a part of moving this stuff
> into a {{hbase-mapreduce}} and {{hbase-shaded-mapreduce}} (HBASE-18697) we
> corrected this gap on the shaded artifact.
> Work around by specifying the class manually
> {code}
> hadoop jar some/path/to/hbase-shaded-server-1.4.11-SNAPSHOT.jar
> org.apache.hadoop.hbase.mapreduce.Driver importtsv
> -Dimporttsv.columns=HBASE_ROW_KEY,family1:column1,family1:column4,family1:column3
> test:example example/ -libjars $(hbase mapredcp)
> {code}
