-----------------------------------
Summary: 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
Fix For: 1.6.0, 1.5.1
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}
