Shengsheng Huang commented on HBASE-6456: ----------------------------------------- {quote} -1 core tests. The patch failed these unit tests: org.apache.hadoop.hbase.client.TestFromClientSide org.apache.hadoop.hbase.coprocessor.TestRegionServerCoprocessorExceptionWithAbort org.apache.hadoop.hbase.catalog.TestMetaReaderEditor org.apache.hadoop.hbase.master.TestMasterNoCluster org.apache.hadoop.hbase.security.access.TestZKPermissionsWatcher {quote} I don't think this patch has something to do with these unit test. Also, those test cases had passed at my local deployment. > Export Utility throws ClassNotFoundException > -------------------------------------------- > > Key: HBASE-6456 > URL: https://issues.apache.org/jira/browse/HBASE-6456 > Project: HBase > Issue Type: Bug > Reporter: Shengsheng Huang > Assignee: Shengsheng Huang > Priority: Minor > Attachments: HBASE-6456.patch > > > The command I ran is as below: > "bin/hbase org.apache.hadoop.hbase.mapreduce.Driver export t1 ./t1" > And I got the following exceptions: > attempt_201207261322_0002_m_000000_0, Status : FAILED > Error: java.lang.ClassNotFoundException: org.apache.hadoop.hbase.util.Bytes > 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) > at java.lang.ClassLoader.loadClass(ClassLoader.java:247) > at org.apache.hadoop.hbase.client.HTable.<init>(HTable.java:150) > at > org.apache.hadoop.hbase.mapreduce.TableInputFormat.setConf(TableInputFormat.java:100) > at > org.apache.hadoop.util.ReflectionUtils.setConf(ReflectionUtils.java:62) > at > org.apache.hadoop.util.ReflectionUtils.newInstance(ReflectionUtils.java:117) > at org.apache.hadoop.mapred.MapTask.runNewMapper(MapTask.java:767) > at org.apache.hadoop.mapred.MapTask.run(MapTask.java:371) > at org.apache.hadoop.mapred.Child$4.run(Child.java:266) > at java.security.AccessController.doPrivileged(Native Method) > at javax.security.au > ... > This exception can be resolved by adding hbase common jar into > HADOOP_CLASSPATH.
