Yes I understand. Indeed I am using a jar file. That error message is a call
stack. The jar file name is "IndexData.jar". The command looks like
hadoop jar IndexData.jar ...orjava -jar IndexData.jar ....

an Apache Project, because Java classes should be in a package, while IndexHDFS
is not part of a package.Apache Lucene/Apache Solr does not have any
package-less classes. Uwe -----Uwe SchindlerH.-H.-Meier-Allee 63, D-28213

Subject: where is IndexHDFS.java Dear Apache Guys,
I am trying to run a hadoop/java command which uses a jar file called
"IndexData.jar". However, I get an error and the call stack shows
Exception in thread "main" java.lang.NullPointerException
at IndexHDFS.indexData(IndexHDFS.java:92)
at IndexHDFS.main(IndexHDFS.java:72)
at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method)
at
sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:57)
at
sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:43)
at java.lang.reflect.Method.invoke(Method.java:606)
at org.apache.hadoop.util.RunJar.main(RunJar.java:156)
So my question is which apache project use the file "IndexHDFS.java"? If you
know, please let me know and save a someone's life! Regards,
Mahmood
