Prashant Kommireddi commented on PIG-2738:
------------------------------------------
Hi Johannes,
Is pig-default.properties on your classpath? Max reducers is set in this file
and should be loaded into Properties object by default.
{code}
public PigServer(ExecType execType) throws ExecException {
this(execType, PropertiesUtil.loadDefaultProperties());
}
{code}
loadDefaultProperties looks for pig-default.properties
{code}
public static void loadDefaultProperties(Properties properties) {
loadPropertiesFromFile(properties,
System.getProperty("user.home") + "/.pigrc");
loadPropertiesFromClasspath(properties, DEFAULT_PROPERTIES_FILE);
{code}
This should be present in your PIG_HOME/conf directory?
> pig.exec.reducers.max has no default value
