Dear sir or madam, I really don't want to bother you because these questions seem "stupid." But I have been troubled by them for a month, so that I can't do the next step. I am very troubled, so I have to send you this very rude mail! Please be forgive me, I urgently need your help now. My question is I can not load data, there are details: 1. Bulk load data When I executed this instruction, the instruction is hadoop jar usr/local/rya.mapreduce-4.0.0-incubting-SNAPSHOT-shaded.jar org.apache.rya.accumulo.mr.RdfFileInputTool -Dac.zk=localhost:2181 -Dac.instance=accumulo -Dac.username=root -Dac.pwd=111111 -Drdf.tablePrefix=triplestore_ -Drdf.format=N-Triples hdfs://$RDF_DATA
there are always out errors about “Exception in thread “main” java.long.ClassNotFoundException: org.apache.rya.accumulo.mr.RdfFileInputTool”. As shown in the picture I find the location of "RdfFileInputTool ", so I add "tools." before "RdfFileInputTool ", the instruction turns to: hadoop jar /usr/local/rya.mapreduce-4.0.0-incubating-SNAPSHOT-shaded.jar org.apache.rya.accumulo.mr.tools.RdfFileInputTool -Drdf.tablePrefix=triplestore_ -Dcb.username=root -Dcb.pwd=111111 -Dcb.instance=accumulo -Dcb.zk=localhost:2181 -Drdf.format=N-Triples hdfs://$RDF_DATA But the errors are: java.lang.NullPointerException: Accumulo instance name [ac.instance] not set. at com.google.common.base.Preconditions.checkNotNull(Preconditions.java:204) at org.apache.rya.accumulo.mr.AbstractAccumuloMRTool.init(AbstractAccumuloMRTool.java:133) at org.apache.rya.accumulo.mr.tools.RdfFileInputTool.run(RdfFileInputTool.java:63) at org.apache.hadoop.util.ToolRunner.run(ToolRunner.java:70) at org.apache.rya.accumulo.mr.tools.RdfFileInputTool.main(RdfFileInputTool.java:55) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:62) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:43) at java.lang.reflect.Method.invoke(Method.java:498) at org.apache.hadoop.util.RunJar.run(RunJar.java:221) at org.apache.hadoop.util.RunJar.main(RunJar.java:136) 2. Web Rest Point The quick start in eht website has told me to use these java codes to load data to REST endpoint, but my question is : I have copy these codes to Eclipse, and put it as a jar to HDFS, but I can not load the data. And the codes like the picture, I tried to run the code in eclipse but it went wrong, so I export these codes as an jar and put this jar to HDFS, but still can't use it.: 3.The accumulo-site.xml likes the picture 4.the accumulo_evn.sh likes the picture 5.My classpath likes the picture 6.environment.properties instance.name=accumulo instance.zk=localhost:2181 instance.username=root instance.password=111111 rya.tableprefix=triplestore_ rya.displayqueryplan=true
