Toshihiro Suzuki commented on HBASE-21182: ------------------------------------------ I think running bin/start-hbase.sh in the source checkout directory is expected, because bin/hbase obviously expects it as the following: {code} # Detect if we are in hbase sources dir in_dev_env=false if [ -d "${HBASE_HOME}/target" ]; then in_dev_env=true fi {code} And it looks like when in_dev_env=true, it adds jars in cached_classpath.txt to the classpath. {code} #Add the development env class path stuff if $in_dev_env; then add_maven_deps_to_classpath "cached_classpath.txt" if [[ $jline_needed ]]; then add_maven_deps_to_classpath "cached_classpath_jline.txt" elif [[ $jruby_needed ]]; then add_maven_deps_to_classpath "cached_classpath_jruby.txt" fi fi {code} This actual path is hbase-build-configuration/target/cached_classpath.txt, and it looks like it's generated by the hbase-assembly module. I think we should not add hbase-shaded-mapreduce.jar to the cached_classpath.txt. I will make a patch not to add hbase-shaded-mapreduce the cached_classpath.txt. > Failed to execute start-hbase.sh > -------------------------------- > > Key: HBASE-21182 > URL: https://issues.apache.org/jira/browse/HBASE-21182 > Project: HBase > Issue Type: Bug > Affects Versions: 3.0.0 > Reporter: Subrat Mishra > Priority: Major > > Built master branch like below: > {code:java} > mvn clean install -DskipTests{code} > Then tried to execute start-hbase.sh failed with NoClassDefFoundError > {code:java} > ./bin/start-hbase.sh > Error: A JNI error has occurred, please check your installation and try again > Exception in thread "main" java.lang.NoClassDefFoundError: > org/apache/hadoop/hbase/shaded/org/eclipse/jetty/server/Connector > at java.lang.Class.getDeclaredMethods0(Native Method) > at java.lang.Class.privateGetDeclaredMethods(Class.java:2701) > at java.lang.Class.privateGetMethodRecursive(Class.java:3048) > at java.lang.Class.getMethod0(Class.java:3018) > at java.lang.Class.getMethod(Class.java:1784) > at sun.launcher.LauncherHelper.validateMainClass(LauncherHelper.java:544) > at sun.launcher.LauncherHelper.checkAndLoadMain(LauncherHelper.java:526) > Caused by: java.lang.ClassNotFoundException: > org.apache.hadoop.hbase.shaded.org.eclipse.jetty.server.Connector{code} > Note: It worked after reverting HBASE-21153 -- This message was sent by Atlassian JIRA (v7.6.3#76005)
