-------------------------------------------------
Guys I'm gotting the exactly same issue.
I will attach some files and scripts that could help reproduce those errors.
I don't know the best approach to reopen the issue.
If someone could help in this.

> Key: PIG-1697
> URL: https://issues.apache.org/jira/browse/PIG-1697
> Project: Pig
> Issue Type: Bug
> Affects Versions: 0.8.0
> Reporter: Ranjit Mathew
>
> If I use a {{log4j.properties}} _without_ the magical line:
> bq. log4j.logger.org.apache.pig=WARN, MyAppender
> Pig 0.8.0 crashes on me and I get:
> bq. Details at logfile: /home/ranjit/src/Pig/stage/pig-0.8.0-SNAPSHOT/pig_1288005234464.log
> This file contains:
> {quote}
> Error before Pig is launched
> ----------------------------
> ERROR 2999: Unexpected internal error. null
> java.lang.NullPointerException
> at org.apache.pig.Main.configureLog4J(Main.java:605)
> at org.apache.pig.Main.run(Main.java:337)
> at org.apache.pig.Main.main(Main.java:107)
> ================================================================================
> {quote}
> Line #605 in {{Main.java}} is:
> bq. backendProps.setProperty("log4j.logger.org.apache.pig.level", logLevel.toString());
> and it turns out that {{logLevel}} is NULL in this case. That in turn is because line #603 contains:
> bq. logLevel = Logger.getLogger("org.apache.pig").getLevel();
> I believe we should use {{Logger.getEffectiveLevel()}} instead.
