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.

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.:
