RE: ENOENT error

Yes, for some reason, although I specify local mode, hadoop is coming into picture.
bash-4.1$ which java/usr/bin/java
bash-4.1$ ls -lrt /usr/bin/javalrwxrwxrwx 1 root root 22 Oct 31 16:17 /usr/bin/java -> /etc/alternatives/java
bash-4.1$ ls -lrt /etc/alternatives/javalrwxrwxrwx 1 root root 46 Oct 31 16:17 /etc/alternatives/java -> /usr/lib/jvm/jre-1.7.0-openjdk.x86_64/bin/java
I tried rest the following the variables:bash-4.1$ export HADOOP_HOME=bash-4.1$ export HADOOP_CONF_DIR=bash-4.1$ pig -x local local-hcc-cidmrn-richer.pig/users/p529444/software/hadoop-1.0.3/bin/hadoop: line 320: /usr/lib/jvm/java-1.7.0-openjdk-1.7.0.9.x86_64: is a directory/users/p529444/software/hadoop-1.0.3/bin/hadoop: line 390: /usr/lib/jvm/java-1.7.0-openjdk-1.7.0.9.x86_64: is a directory/users/p529444/software/hadoop-1.0.3/bin/hadoop: line 390: exec: /usr/lib/jvm/java-1.7.0-openjdk-1.7.0.9.x86_64: cannot execute: Success

If I don't reset HADOOP_HOME and HADOOP_CONF_DIR variables, I get the following errors:

If I set my  JAVA_HOME in the following way I get this:export JAVA_HOME="/usr/lib/jvm/jre-1.7.0-openjdk.x86_64/bin/java"bash-4.1$ pig -x local local-hcc-cidmrn-richer.pigException in thread "main" java.io.IOException: Permission denied at java.io.UnixFileSystem.createFileExclusively(Native Method) at java.io.File.createTempFile(File.java:1879) at org.apache.hadoop.util.RunJar.main(RunJar.java:115)
