> Key: SPARK-7595
> URL: https://issues.apache.org/jira/browse/SPARK-7595
> Project: Spark
> Issue Type: Bug
> Components: SQL
> Reporter: Weizhong
> Priority: Minor
> Fix For: 1.4.0

> for example:
> table: src(key string, value string)
> sql: with v1 as(select key, count(value) over (partition by key) cnt_val from
> src), v2 as(select v1.key, v1_lag.cnt_val from v1, v1 v1_lag where v1.key =
> v1_lag.key) select * from v2 limit 5;
> then will analyze fail when resolving conflicting references in Join:
> 'Limit 5
> 'Project [*]
> 'Subquery v2
> 'Project ['v1.key,'v1_lag.cnt_val]
> 'Filter ('v1.key = 'v1_lag.key)
> 'Join Inner, None
> Subquery v1
> Project [key#95,cnt_val#94L]
> Window [key#95,value#96],
> [HiveWindowFunction#org.apache.hadoop.hive.ql.udf.generic.GenericUDAFCount(value#96)
> WindowSpecDefinition [key#95], [], ROWS BETWEEN UNBOUNDED PRECEDING AND
> UNBOUNDED FOLLOWING AS cnt_val#94L], WindowSpecDefinition [key#95], [], ROWS
> BETWEEN UNBOUNDED PRECEDING AND UNBOUNDED FOLLOWING
> Project [key#95,value#96]
> MetastoreRelation default, src, None
> Subquery v1_lag
> Subquery v1
> Project [key#97,cnt_val#94L]
> Window [key#97,value#98],
> [HiveWindowFunction#org.apache.hadoop.hive.ql.udf.generic.GenericUDAFCount(value#98)
> WindowSpecDefinition [key#97], [], ROWS BETWEEN UNBOUNDED PRECEDING AND
> UNBOUNDED FOLLOWING AS cnt_val#94L], WindowSpecDefinition [key#97], [], ROWS
> BETWEEN UNBOUNDED PRECEDING AND UNBOUNDED FOLLOWING
> Project [key#97,value#98]
> MetastoreRelation default, src, None
> Conflicting attributes: cnt_val#94L
