Install PIG on one node

Question

I installed Hadoop (1.0.2) for a single node on Windows 7 with Cygwin and it works. However, I cannot get PIG (0.10.0) to see Hadoop.

1) "Error: JAVA_HOME is not set." 

I added this line to the pigs (in the basket): export JAVA_HOME = / cygdrive / c / PROGRA ~ 1 / Java / jdk1.7.0_05

 2) 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 

I tried to add below line to the pig, and it still does not find hadoop. What should I do?

 export PIG_HOME="/cygdrive/c/pig-0.10.0" export PATH=$PATH:$PIG_HOME/bin export PIG_CLASSPATH=/cygdrive/hadoop/hadoop-1.0.2/conf 

Answer 1

You may need to add your Hadoop installation to your path. eg.

 export HADOOP_INSTALL=/Users/yourname/dev/hadoop-0.20.203.0 export PATH=$PATH:$HADOOP_INSTALL/bin 

Answer 2

I had the same problem with pig-0.11. This seems to be a special cygwin issue.

Copying pig-0.11.1-withouthadoop to pigs using houtouthadoop.jar under PIG_HOME fixed the problem for me

Answer 3

I tried to configure PIG on my gateway machine that is running Windows 7.

This issue is very specific to Cygwin.

After breaking my head for a couple of hours, I found a solution:

The solution is very simple.

Just rename the jar file under "pig-0.10.1-withouthadoop.jar" to "pig-withouthadoop.jar".

Alternatively, you can add the path: (hadoop directory) \ hadoop-vvv \ bin to the environment variables manually in Windows 7. This will solve this problem.

 which: no hadoop in (/usr/local/b.....) 

Answer 5

I had a similar problem with Pig 0.12.0 (and Hadoop 1.0.3) installed on Fedora 19. When I tried to execute any Pig command, for example

 pig -help 

I was getting the error:

 Cannot locate pig-withouthadoop.jar. do 'ant jar-withouthadoop.jar', and try again 

The Hadoop and Pig / bin folders were correctly included in my PATH.

Just copying the pig-0.12.0-withouthadoop.jar folder to the PIG_HOME folder fixed the problem for me.

Answer 6

You should visit this to install pig 12 on hadoop 2.2.0 without any errors, as it compiles the pig library for the specified hadoop version.

After completing the steps, you will get a running pig without any grunt errors.

Just enjoy it.
