[jira] [Created] (MAPREDUCE-3727) jobtoken location property in
jobconf refers to wrong jobtoken file
jobtoken location property in jobconf refers to wrong jobtoken file
-------------------------------------------------------------------
Key: MAPREDUCE-3727
URL: https://issues.apache.org/jira/browse/MAPREDUCE-3727
Project: Hadoop Map/Reduce
Issue Type: Bug
Components: security
Affects Versions: 1.0.0
Reporter: Alejandro Abdelnur
Assignee: Alejandro Abdelnur
Priority: Critical
Oozie launcher job (for MR/Pig/Hive/Sqoop action) reads the location of the jobtoken file from the *HADOOP_TOKEN_FILE_LOCATION* ENV var and seeds it as the *mapreduce.job.credentials.binary* property in the jobconf that will be used to launch the real (MR/Pig/Hive/Sqoop) job.
The MR/Pig/Hive/Sqoop submission code (via Hadoop job submission) uses correctly the injected *mapreduce.job.credentials.binary* property to load the credentials and submit their MR jobs.
The problem is that the *mapreduce.job.credentials.binary* property also makes it to the tasks of the MR/Pig/Hive/Sqoop MR jobs.
If for some reason the MR/Pig/Hive/Sqoop MR code does some logic that triggers the credential loading, because the property is set, the credential loading fails trying to load a jobtoken file of the launcher job which does not exists in the context of the MR/Pig/Hive/Sqoop jobs.
More specifically, we are seeing this happening with certain hive queries that trigger a conditional code within their RowContainer which then uses the FileInputFormat.getSplits() and then the TokenCache tries to load credentials for a file that is for the wrong job.
