Hadoop, mail # dev - Is there any way to add jar when invoking hadoop command

Is there any way to add jar when invoking hadoop command

Hi all,

When I use command "hadoop fs -text" I need to add extra jar to CLASSPATH,
because there's custom type in my sequence file. One way is that copying jar
to $HADOOP_HOME/lib
But in my case, I am not administrator, so I do not have the permission to
copy files under $HADOOP_HOME/lib

Is there any other ways to add extra jar to CLASSPATH ?

Another work around I can think of is that have my own copy of hadoop, and
copy extra jars to my hadoop. But it result into more maintenance effort
