[jira] [Updated] (HIVE-6546) WebHCat job submission for pig with -useHCatalog argument fails on Windows

     [ https://issues.apache.org/jira/browse/HIVE-6546?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Eric Hanson updated HIVE-6546:
------------------------------

    Description: 
On a one-box windows setup, do the following from a powershell prompt:

cmd /c curl.exe -s `
  -d user.name=hadoop `
  -d arg=-useHCatalog `
  -d execute="emp = load '/data/emp/emp_0.dat'; dump emp;" `
  -d statusdir="/tmp/webhcat.output01" `
  'http://localhost:50111/templeton/v1/pig' -v

The job fails with error code 7, but it should run. 

I traced this down to the following. In the job configuration for the TempletonJobController, we have templeton.args set to

cmd,/c,call,C:\\hadoop\\\\pig-0.11.0.1.3.0.0-0846/bin/pig.cmd,-D__WEBHCAT_TOKEN_FILE_LOCATION__="-useHCatalog",-execute,"emp = load '/data/emp/emp_0.dat'; dump emp;"

Notice the = sign before "-useHCatalog". I think this should be a comma.

The bad string D__WEBHCAT_TOKEN_FILE_LOCATION__="-useHCatalog" gets created in  org.apache.hadoop.util.GenericOptionsParser.preProcessForWindows().

It happens at line 434:
{code}
      } else {
          if (i < args.length - 1) {
            prop += "=" + args[++i];   // RIGHT HERE! at iterations i = 37, 38
          }
        }
{code}

Bug is here:
{code}
      if (prop != null) {
        if (prop.contains("=")) {  // -D__WEBHCAT_TOKEN_FILE_LOCATION__ does not contain equal, so else branch is run and appends ="-useHCatalog",
          // everything good
        } else {
          if (i < args.length - 1) {
            prop += "=" + args[++i];
          }
        }
        newArgs.add(prop);
      }
{code}
One possible fix is to change the string constant org.apache.hcatalog.templeton.tool.TempletonControllerJob.TOKEN_FILE_ARG_PLACEHOLDER to have an "=" sign in it. Or, preProcessForWindows() itself could be changed.
