    Description

      Running Pig scripts through Grunt works without hiccup but I have a utility program that runs commands through PigServer. When running that way, I run into two problems.

      The first, which I can hack around, is that I need to pass in to PigServer the hbase configuration. When I do this with ConfigurationUtil.toProperties(hbaseConfig), the new properties get passed in-not the deprecated ones. Later on down the road, Pig looks for fs.default.name which is the deprecated property for fs.defaultfs and throws [1] The hack is to back map the fs.default.name property to the value of fs.defaultfs after calling ConfigurationUtil.toProperties();

      That brings me to the second problem which I haven't been able to hack around - When PigServer runs, it throws the exception[2]. Poking through the code, there is no longer an org.apache.hadoop.mapred.jobcontrol.JobControl.addJob() method distributed with hadoop 0.23-only an org.apache.hadoop.mapred.jobcontrol.JobControl.addJobs() method-which also appears to be deprecated.

      Again, Grunt works fine-just PigServer shows these problems. Has anyone resolved this? Or should I log a bug?

      Thanks!
