and i have installed lzop-1.03,lzo-2.06,
kevinweil-hadoop-lzo-6bb1b7f.zip have builded successfully,i have copied hadoop-lzo-0.4.15.jar to /home/hadoop/hadoop/lib/lzo(my hadoop home is /home/hadoop/hadoop),and copied lib/native/Linux-i386-32 to /home/hadoop/hadoop/lib/native/Linux-i386-32(my system is 32 bit).and my /etc/profile is:

my hadoop-env.sh is

Set Hadoop-specific environment variables here.

The only required environment variable is JAVA_HOME. All others are

optional. When running a distributed configuration it is best to

set JAVA_HOME in this file, so that it is correctly defined on

remote nodes.

The java implementation to use. Required.

export JAVA_HOME=/usr/lib/jvm/java-1.6.0_31-sun
export HADOOP_OPTS=-Djava.net.preferIPv4Stack=true

Extra Java CLASSPATH elements. Optional.

export HADOOP_HOME=/home/hadoop/hadoop

export HADOOP_CLASSPATH=/home/hadoop/hadoop/lib/hadoop-lzo-0.4.15.jar

export LD_LIBRARY_PATH=/home/hadoop/hadoop/lib/native

export HADOOP_LIBRARY_PATH=/home/hadoop/hadoop/lib/native/Linux-i386-32/lib:/home/hadoop/hadoop/lib/native:/home/hadoop/hadoop/lib

The maximum amount of heap to use, in MB. Default is 1000.

export HADOOP_HEAPSIZE=2000

Extra Java runtime options. Empty by default.

export HADOOP_OPTS=-server

Command specific options appended to HADOOP_OPTS when specified

export HADOOP_NAMENODE_OPTS="-Dcom.sun.management.jmxremote $HADOOP_NAMENODE_OPTS"
export HADOOP_SECONDARYNAMENODE_OPTS="-Dcom.sun.management.jmxremote $HADOOP_SECONDARYNAMENODE_OPTS"

export HADOOP_JOBTRACKER_OPTS="-Dcom.sun.management.jmxremote $HADOOP_JOBTRACKER_OPTS"

export HADOOP_TASKTRACKER_OPTS=

The following applies to multiple commands (fs, dfs, fsck, distcp etc)

export HADOOP_CLIENT_OPTS

Extra ssh options. Empty by default.

export HADOOP_SSH_OPTS="-o ConnectTimeout=1 -o SendEnv=HADOOP_CONF_DIR"

Where log files are stored. $HADOOP_HOME/logs by default.

export HADOOP_LOG_DIR=${HADOOP_HOME}/logs

File naming remote slave hosts. $HADOOP_HOME/conf/slaves by default.

export HADOOP_SLAVES=${HADOOP_HOME}/conf/slaves

host:path where hadoop code should be rsync'd from. Unset by default.

export HADOOP_MASTER=master:/home/$USER/src/hadoop

Seconds to sleep between slave commands. Unset by default. This

can be useful in large clusters, where, e.g., slave rsyncs can

otherwise arrive faster than the master can service them.

export HADOOP_SLAVE_SLEEP=0.1

The directory where pid files are stored. /tmp by default.

export HADOOP_PID_DIR=/var/hadoop/pids

A string representing this instance of hadoop. $USER by default.

export HADOOP_IDENT_STRING=$USER

The scheduling priority for daemon processes. See 'man nice'.

export HADOOP_NICENESS=10

no matter I try it on the cluster or on a single node ,the problem is always exits,i don't know why ,please help me!!1
