> This is a regression of PIG-3525 where I moved the initialization of PigStats into the PigServer constructor. The problem is that if Pig fails even before PigServer is created, PigStats remains null resulting in NPE in PigStatsUtil.
> {code:title=PigStatsUtil}
>     public static void setErrorMessage(String msg) {
>         PigStats.get().setErrorMessage(msg); //---> PigStats.get() returns null
>     }
>     public static void setErrorCode(int code) {
>         PigStats.get().setErrorCode(code); //---> PigStats.get() returns null
>     }
> {code}
> To reproduce the issue, run the following command-
> {code}
> pig -x -f script.pig  #---> Note -x is missing the argument
> {code}
> The stack trace looks like this-
> {code}
> Exception in thread "main" java.lang.NullPointerException
> 	at org.apache.pig.tools.pigstats.PigStatsUtil.setErrorMessage(PigStatsUtil.java:145)
> 	at org.apache.pig.Main.run(Main.java:618)
> 	at org.apache.pig.Main.main(Main.java:156)
> {code}
