[Solved-2 Solutions] Installing PIG on single node ?
Problem:
- If you installed Hadoop (1.0.2) for a single node on Windows 7 with Cygwin, and it is working. However, you cannot get PIG (0.10.0) to see the Hadoop.
1) "Error: JAVA_HOME is not set."
- Added this line to pig (under bin):
export JAVA_HOME=/cygdrive/c/PROGRA~1/Java/jdk1.7.0_052) which: no hadoop in (/usr/local/b.....)
cygpath: cannot create short name of C:\pig-0.10.0\logs
Cannot locate pig.jar. do 'ant jar', and try again
- If you tried adding below lines to pig and it is still not finding hadoop. What should you do?
export PIG_HOME="/cygdrive/c/pig-0.10.0"
export PATH=$PATH:$PIG_HOME/bin
Solution 1:
- We might need to add your Hadoop install to your path as well.
Example
export HADOOP_INSTALL=/Users/yourname/dev/hadoop-0.20.203.0
export PATH=$PATH:$HADOOP_INSTALL/bin
Solution 2:
- Just rename the jar file under ”pig-0.10.1-withouthadoop.jar” to “pig-withouthadoop.jar”.
