Yin Huai created SPARK-2474:
-------------------------------
Summary: In some cases, the Analyzer failed to resolve a table
registered in OverrideCatalog
Key: SPARK-2474
URL: https://issues.apache.org/jira/browse/SPARK-2474
Project: Spark
Issue Type: Bug
Components: SQL
Affects Versions: 1.0.1
Reporter: Yin Huai
To reproduce the error, execute the following code in hive/console...
{code}
val m = hql("select key from src")
m.registerAsTable("m")
hql("select m.key from m")
{code}
Then, you will see
{code}
org.apache.spark.sql.catalyst.errors.package$TreeNodeException: Unresolved
attributes: 'm.key, tree:
Project ['m.key]
LowerCaseSchema
Project [key#6]
LowerCaseSchema
MetastoreRelation default, src, None

{code}
However, if you run
{code}
hql("select tmp.key from m tmp")
{code}
We are fine.
