Yi Liang commented on HBASE-18791: ---------------------------------- I found this issue when I try to test HBASE-16894 on real cluster. {quote}How did you test it sir?{quote} 1. Do you mean how I test this patch? After I changed the code, I build a tarball to see if this test jar is included in it. 2. I guess you may mean something else, I usually use docker to test something on real cluster. I have a docker image that can 'Run Distributed HBase Cluster within Docker Containers'; See https://github.com/YiSoEasy/docker-hbase I put the new tarball into my repo and modify a little bit code in DockerFile(in above branch) to download the new hbase tarball. So I can build a real distributed hbase cluster with the latest hbase version, and then testing ;) Hope I answer your question correctly. {quote}We might be missing other libs given we added a few modules recently.{quote} Maybe, I saw some errors below, when I try to run hbase pe. {quote} 2017-09-12 00:10:52,877 INFO [main] mapreduce.Job: Task Id : attempt_1505170797673_0009_m_000000_0, Status : FAILED Error: java.io.IOException: java.lang.reflect.InvocationTargetException at org.apache.hadoop.hbase.client.ConnectionFactory.createConnection(ConnectionFactory.java:221) at org.apache.hadoop.hbase.client.ConnectionFactory.createConnection(ConnectionFactory.java:114) at org.apache.hadoop.hbase.PerformanceEvaluation$EvaluationMapTask.map(PerformanceEvaluation.java:311) at org.apache.hadoop.hbase.PerformanceEvaluation$EvaluationMapTask.map(PerformanceEvaluation.java:264) at org.apache.hadoop.mapreduce.Mapper.run(Mapper.java:146) at org.apache.hadoop.mapred.MapTask.runNewMapper(MapTask.java:787) at org.apache.hadoop.mapred.MapTask.run(MapTask.java:341) at org.apache.hadoop.mapred.YarnChild$2.run(YarnChild.java:164) at java.security.AccessController.doPrivileged(Native Method) at javax.security.auth.Subject.doAs(Subject.java:422) at org.apache.hadoop.security.UserGroupInformation.doAs(UserGroupInformation.java:1657) at org.apache.hadoop.mapred.YarnChild.main(YarnChild.java:158) Caused by: java.lang.reflect.InvocationTargetException at sun.reflect.NativeConstructorAccessorImpl.newInstance0(Native Method) at sun.reflect.NativeConstructorAccessorImpl.newInstance(NativeConstructorAccessorImpl.java:62) at sun.reflect.DelegatingConstructorAccessorImpl.newInstance(DelegatingConstructorAccessorImpl.java:45) at java.lang.reflect.Constructor.newInstance(Constructor.java:423) at org.apache.hadoop.hbase.client.ConnectionFactory.createConnection(ConnectionFactory.java:219) ... 11 more Caused by: java.lang.NoClassDefFoundError: org/apache/commons/lang3/ArrayUtils at org.apache.hadoop.hbase.HConstants.<clinit>(HConstants.java:1144) at org.apache.hadoop.hbase.client.ConnectionUtils.getPauseTime(ConnectionUtils.java:84) at org.apache.hadoop.hbase.client.AsyncProcess.<init>(AsyncProcess.java:209) at org.apache.hadoop.hbase.client.ConnectionImplementation.<init>(ConnectionImplementation.java:266) ... 16 more Caused by: java.lang.ClassNotFoundException: org.apache.commons.lang3.ArrayUtils at java.net.URLClassLoader.findClass(URLClassLoader.java:381) at java.lang.ClassLoader.loadClass(ClassLoader.java:424) at sun.misc.Launcher$AppClassLoader.loadClass(Launcher.java:335) at java.lang.ClassLoader.loadClass(ClassLoader.java:357) {quote} > HBASE_HOME/lib does not contain hbase-mapreduce-${project.version}-tests.jar > ---------------------------------------------------------------------------- > > Key: HBASE-18791 > URL: https://issues.apache.org/jira/browse/HBASE-18791 > Project: HBase > Issue Type: Bug > Affects Versions: 2.0.0 > Reporter: Yi Liang > Assignee: Yi Liang > Attachments: hbase-18791-master-v1.patch > > > hbase pe > Error: Could not find or load main class > org.apache.hadoop.hbase.PerformanceEvaluation > hbase ltt > Error: Could not find or load main class > org.apache.hadoop.hbase.util.LoadTestTool > Those class are in hbase-mapreduce-test.jar -- This message was sent by Atlassian JIRA (v6.4.14#64029)
