nkeywal created HBASE-7637:
------------------------------
Summary: hbase-hadoop1-compat conflicts with -Dhadoop.profile=2.0
Key: HBASE-7637
URL: https://issues.apache.org/jira/browse/HBASE-7637
Project: HBase
Issue Type: Bug
Components: build
Affects Versions: 0.96.0
Reporter: nkeywal
Priority: Critical
I'm unclear on the root cause / fix. Here is the scenario:
{noformat}
mvn clean package install -Dhadoop.profile=2.0 -DskipTests
bin/start-hbase.sh
{noformat}
fails with
{noformat}
Caused by: java.lang.ClassNotFoundException:
org.apache.hadoop.metrics2.lib.MetricMutable
at java.net.URLClassLoader$1.run(URLClassLoader.java:202)
at java.security.AccessController.doPrivileged(Native Method)
at java.net.URLClassLoader.findClass(URLClassLoader.java:190)
at java.lang.ClassLoader.loadClass(ClassLoader.java:306)
at sun.misc.Launcher$AppClassLoader.loadClass(Launcher.java:301)
{noformat}
doing
{noformat}
rm -rf hbase-hadoop1-compat/target/
{noformat}
makes it work.
In the pom.xml, we never reference hadoop2-compat. But doing so does not help:
hadoop1-compat is compiled and takes precedence over hadoop2...
