Pig installation not working

I have installed Pig 0.12.0 on my box. I have also installed Java and Hadoop and have set JAVA_HOME and HADOOP_HOME paths. When Igo to the bin directory of pig installation and type the following command on my command prompt:

pig -help

it errors out with the following message:

The system cannot find the path specified.
'-Xmx1000M' is not recognized as an internal or external command,
operable program or batch file.

Whats wrong? Should I be using cygwin? (that didnt work either)

This will solve your problem...

1.Download PIG ->http://mirrors.estointernet.in/apache/pig/pig-0.16.0/    
2.Set properties->    
  PIG_HOME=C:\Users\lenovo\Downloads\pig-0.16.0\pig-0.16.0    
  path=C:\Users\lenovo\Downloads\pig-0.16.0\pig-0.16.0\bin    
  PIG_CLASSPATH=C:\Users\lenovo\Downloads\hadoop-2.7.3\hadoop-2.7.3\etc\hadoop(Where 
                core-site.xml,mapred-site.xml are present)    
3.    
  ->open the file pig.cmd(From bin directory of PIG)   
  ->look for the line set HADOOP_BIN_PATH=%HADOOP_HOME%\bin    
  ->replace this with set HADOOP_BIN_PATH=%HADOOP_HOME%\libexec    
4.Now in command prompt give->pig    `enter code here`

I know this is a very late reply, but hope this will help someone to configure pig

Using OS Windows 8.1 ProN x64

Note -> Life will be easier in configuration, if your directory path doesn't contains a whitespace.

Steps to configure Pig with Hadoop

java path location (jdk1.8.0_151)

JAVA_HOME C:\Java\jdk1.8.0_151

python path location (Python27)

C:\Python27

ant path location (apache-ant-1.10.1)

ANT_HOME F:\Hadoop\apache-ant-1.10.1

hadoop path location (hadoop-2.8.2)

HADOOP_HOME F:\Hadoop\hadoop-2.8.2

HADOOP_COMMON_LIB_NATIVE_DIR %HADOOP_HOME%\lib\native

HADOOP_CONF_DIR %HADOOP_HOME%\etc\hadoop

pig path location (pig-0.17.0)

PIG_HOME F:\Hadoop\pig-0.17.0

System Variables Path

C:\Python27\;C:\Python27\Scripts;C:\Java\jdk1.8.0_151\bin;F:\Hadoop\hadoop-2.8.2\bin;F:\Hadoop\hadoop-2.8.2\sbin;F:\Hadoop\pig-0.17.0\bin;

  1. explore winutils-master.zip on github, pull and download, extract to %HADOOP_HOME%\bin directory
  2. open %PIG_HOME%\bin\pig.cmd using notepad/notepad++ (recommended notepad++)

  3. change the below said line and later save it, close it -

    "set HADOOP_BIN_PATH=%HADOOP_HOME%\bin" to "set HADOOP_BIN_PATH=%HADOOP_HOME%\libexec"

  4. so now the pig will access hadoop-config.cmd inside %HADOOP_HOME% path as we configured earlier.
  5. start-all.cmd from hadoop to start the cluster with all dependencies.
  6. go to %PIG_HOME%/bin, check with pig -help (if results are as parameterized).
  7. pig (Enter to grunt shell.)

Note -> there are much possibilities to get below exception, if you don't configure as above.

'F:\Hadoop\hadoop-2.8.2\bin\hadoop-config.cmd' is not recognized as an internal or external command, operable program or batch file. 

'-Xmx1000M' is not recognized as an internal or external command, operable program or batch file.

hope, these illustrated steps will help you to configure and start the pig grunt shell, thanks.

I just installed Pig 0.12.1 on Windows 7 without Hadoop installed. I also got this error message and resolved it by setting the "JAVA" environment variable to point to the java.exe executable.

In my case, I set JAVA=C:\Progra~1\Java\jdk1.8.0_05\bin\java.exe

I also set: 

JAVA_HOME=C:\Progra~1\Java\jdk1.8.0_05
PIG_HOME=C:\pig-0.12.1  (This is where I extracted pig-0.12.1.tar.gz)

and added C:\pig-0.12.1\bin to my PATH environment variable.

Hope this helps anyone else with this issue!
