Answer 1

If you are allowed to set HADOOP_CLASSPATH then

export HADOOP_CLASSPATH=/path/to/jar/myjar.jar:$HADOOP_CLASSPATH; \
    hadoop fs -text /path/in/HDFS/to/my/file

will do the job. Since in your case this variable is overridden in hadoop-env.sh therefore, consider using the -libjars option instead:

hadoop fs -libjars /path/to/jar/myjar.jar -text /path/in/HDFS/to/my/file

Alternatively invoke FsShell manually:

java -cp $HADOOP_HOME/lib/*:/path/to/jar/myjar.jar:$CLASSPATH \
org.apache.hadoop.fs.FsShell -conf $HADOOP_HOME/conf/core-site.xml \
-text /path/in/HDFS/to/my/file
