Examples of org.apache.pig.StoreFuncInterface.relToAbsPathForStoreLocation()

org.apache.pig.StoreFuncInterface.relToAbsPathForStoreLocation()
This method is called by the Pig runtime in the front end to convert the output location to an absolute path if the location is relative. The StoreFuncInterface implementation is free to choose how it converts a relative location to an absolute location since this may depend on what the location string represent (hdfs path or some other data source). The static method {@link LoadFunc#getAbsolutePath} provides a default implementation for hdfs and hadoop local file system and it can be used to implement this method. @param location location as provided in the "store" statement of the script @param curDir the current working direction based on any "cd" statementsin the script before the "store" statement. If there are no "cd" statements in the script, this would be the home directory -
```
/user/ 
```
@return the absolute location based on the arguments passed @throws IOException if the conversion is not possible
