Eric Hanson commented on HIVE-6546:
-----------------------------------
I'm not sure I understand what you mean. Can you elaborate? The placeholder is
getting substituted or eliminated by the templeton controller job.
If I run this simple Pig script from WebHCat:
emp = load 'wasbs://eha...@ehans7.blob.core.windows.net/data/emp_0.dat'; dump
emp;
Then I see this in the templeton controller job configuration:
templeton.args
cmd,/c,call,C:\\apps\\dist\\pig-0.12.0.2.0.7.0-1551/bin/pig.cmd,-D__WEBHCAT_TOKEN_FILE_LOCATION__=-execute,"emp
= load 'wasbs://eha...@ehans7.blob.core.windows.net/data/emp_0.dat'; dump
emp;"
And I see this in the Pig job configuration for the job spawned by the
templeton controller job:
pig.cmd.args
-Dmapreduce.job.credentials.binary=/c:/hdfs/nm-local-dir/usercache/ehans/appcache/application_1395867453549_0007/container_1395867453549_0007_01_000002/container_tokens
-execute emp = load
'wasbs://eha...@ehans7.blob.core.windows.net/data/emp_0.dat'; dump emp;
> WebHCat job submission for pig with -useHCatalog argument fails on Windows

> Key: HIVE-6546
> URL: https://issues.apache.org/jira/browse/HIVE-6546
> Project: Hive
> Issue Type: Bug
> Components: WebHCat
> Affects Versions: 0.11.0, 0.12.0, 0.13.0
> Environment: HDInsight deploying HDP 1.3:
> c:\apps\dist\pig-0.11.0.1.3.2.0-05
> Also on Windows HDP 1.3 one-box configuration.
> Reporter: Eric Hanson
> Assignee: Eric Hanson
> Fix For: 0.13.0
>
> Attachments: HIVE-6546.01.patch, HIVE-6546.02.patch,
> HIVE-6546.03.patch, HIVE-6546.03.patch

>
> 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.
