[jira] [Created] (HIVE-28409) Column lineage when creating view is missing if atlas HiveHook is set

Krisztian Kasa created HIVE-28409:
-------------------------------------

             Summary: Column lineage when creating view is missing if atlas HiveHook is set
                 Key: HIVE-28409
                 URL: https://issues.apache.org/jira/browse/HIVE-28409
             Project: Hive
          Issue Type: Bug
          Components: lineage
            Reporter: Krisztian Kasa
            Assignee: Krisztian Kasa


Column lineage info is collected by {{{}org.apache.hadoop.hive.ql.optimizer.lineage.Generator{}}}. This is called during Hive optimizations and view creation if one of these conditions is met:
{code:java}
hiveConf.getBoolVar(HiveConf.ConfVars.HIVE_LINEAGE_INFO)
        || postExecHooks.contains("org.apache.hadoop.hive.ql.hooks.PostExecutePrinter")
        || postExecHooks.contains("org.apache.hadoop.hive.ql.hooks.LineageLogger")
        || postExecHooks.contains("org.apache.atlas.hive.hook.HiveHook")
{code}
[https://github.com/apache/hive/blob/09553fca66ff69ff870c8a181750b70d81a8640e/ql/src/java/org/apache/hadoop/hive/ql/optimizer/Optimizer.java#L78-L81]
and 
[https://github.com/apache/hive/blob/09553fca66ff69ff870c8a181750b70d81a8640e/ql/src/java/org/apache/hadoop/hive/ql/parse/SemanticAnalyzer.java#L13226-L13228]

However HIVE-17125 introduced more conditions which affects only the {{org.apache.atlas.hive.hook.HiveHook}}
[https://github.com/apache/hive/blob/09553fca66ff69ff870c8a181750b70d81a8640e/ql/src/java/org/apache/hadoop/hive/ql/optimizer/lineage/Generator.java#L75-L86]
 

Later HIVE-23244 changed the code handles view creation. Since there are no tests for testing view creation when {{org.apache.atlas.hive.hook.HiveHook}} is specified at all the new code skips column lineage info collection.
The tests we have for testing column lineage info collection are using [LineageLogger.java|https://github.com/apache/hive/blob/master/ql/src/java/org/apache/hadoop/hive/ql/hooks/LineageLogger.java] which doesn't have any restriction in the Generator so column lineage info is always collected when LineageLogger is set.
