Sean Busbey created HBASE-23147: ----------------------------------- 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} -- This message was sent by Atlassian Jira (v8.3.4#803005)
