Lorand Bendig created HIVE-8484: ----------------------------------- Summary: HCatalog throws an exception if Pig job is of type 'fetch' Key: HIVE-8484 URL: https://issues.apache.org/jira/browse/HIVE-8484 Project: Hive Issue Type: Bug Components: HCatalog Affects Versions: 0.14.0 Reporter: Lorand Bendig Fix For: 0.14.0
When Pig tries to retrieve result in fetch mode through HCatalog then HCatLoader#setLocation(String location, Job job) can't set the outputschema because HCatUtil#checkJobContextIfRunningFromBackend(job) always returns false : {code} public static boolean checkJobContextIfRunningFromBackend(JobContext j) { if (j.getConfiguration().get("mapred.task.id", "").equals("") && !("true".equals(j.getConfiguration().get("pig.illustrating")))) { return false; } return true; } {code} This is because in fetch mode we don't have a mapred.task.id. A null outputschema will raise an exception when HCatBaseLoader#getNext() is called: (ERROR 6018: Error converting read value to tuple). -- This message was sent by Atlassian JIRA (v6.3.4#6332)
