I tried to compile the following program (example program from a hadoop book) on my linix server where I have Haddop installed: I get the errors: $javac PutMerge.java PutMerge.java:2: package org.apache.hadoop.conf does not exist import org.apache.hadoop.conf.Configuration; ^ PutMerge.java:3: package org.apache.hadoop.fs does not exist import org.apache.hadoop.fs.FSDataInputStream; ^ PutMerge.java:4: package org.apache.hadoop.fs does not exist import org.apache.hadoop.fs.FSDataOutputStream; ^ PutMerge.java:5: package org.apache.hadoop.fs does not exist import org.apache.hadoop.fs.FileStatus; ^ PutMerge.java:6: package org.apache.hadoop.fs does not exist import org.apache.hadoop.fs.FileSystem; ^ PutMerge.java:7: package org.apache.hadoop.fs does not exist import org.apache.hadoop.fs.Path; I have $HADOOP_HOME set u: $echo $HADOOP_HOME /usr/lib/hadoop Could you please suggest how to compile this program? Thanks a lot.
