Markus Jelsma commented on NUTCH-1078:
--------------------------------------

Strange:

{code}
    [javac] 
/home/markus/projects/apache/nutch/branches/branch-1.4/src/java/org/apache/nutch/fetcher/Fetcher.java:531:
 cannot find symbol
    [javac] symbol  : method fatal(java.lang.String,java.io.IOException)
    [javac] location: interface org.slf4j.Logger
    [javac]               LOG.fatal("QueueFeeder error reading input, record " 
+ cnt, e);
    [javac]                  ^
    [javac] 
/home/markus/projects/apache/nutch/branches/branch-1.4/src/java/org/apache/nutch/fetcher/Fetcher.java:788:
 cannot find symbol
    [javac] symbol  : method isFatalEnabled()
    [javac] location: interface org.slf4j.Logger
    [javac]         if (LOG.isFatalEnabled()) {
{code}

A lot of errors about these two fatal methods.

> Whilst working on another issue, I noticed that some classes still import and 
> use commons logging for example HttpBase.java
> {code}
> import java.util.*;
> // Commons Logging imports
> import org.apache.commons.logging.Log;
> import org.apache.commons.logging.LogFactory;
> // Nutch imports
> import org.apache.nutch.crawl.CrawlDatum;
> {code}
> At this stage I am unsure how many (if any others) still import and reply 
> upon commons logging, however they should be upgraded to slf4j for branch-1.4.
