Julien Baley commented on SPARK-13046:
--------------------------------------
Sorry it took me so long to come back to you.
We're using Hive (and Java), and I'm calling the
`hiveContext.createExternalTable("table_name", "s3://bucket/some_path/",
"parquet");`, i.e. I believe I'm passing the correct path and then Spark
perhaps infers something wrongly in the middle?
I don't think I have a way to set basePath from there? [~yhuai], do you mean
calling `sqlContext.read.option(key, value)`? Is there a way I can access the
SQLContext from my HiveContext?

> Key: SPARK-13046
> URL: https://issues.apache.org/jira/browse/SPARK-13046
> Project: Spark
> Issue Type: Bug
> Components: Spark Core
> Affects Versions: 1.6.0
> Reporter: Julien Baley
>
> Hello,
> I have a list of files in s3:
> {code}
> s3://bucket/some_path/date_received=2016-01-13/fingerprint=2f6a09d370b4021d/{_SUCCESS,metadata,some
> parquet files}
> s3://bucket/some_path/date_received=2016-01-14/fingerprint=2f6a09d370b4021d/{_SUCCESS,metadata,some
> parquet files}
> s3://bucket/some_path/date_received=2016-01-15/fingerprint=2f6a09d370b4021d/{_SUCCESS,metadata,some
> parquet files}
> {code}
> Until 1.5.2, it all worked well and passing s3://bucket/some_path/ (the same
> for the three lines) would correctly identify 2 pairs of key/value, one
> `date_received` and one `fingerprint`.
> From 1.6.0, I get the following exception:
> {code}
> assertion failed: Conflicting directory structures detected. Suspicious paths
> s3://bucket/some_path/date_received=2016-01-13
> s3://bucket/some_path/date_received=2016-01-14
> s3://bucket/some_path/date_received=2016-01-15
> {code}
> That is to say, the partitioning code now fails to identify
> date_received=2016-01-13 as a key/value pair.
> I can see that there has been some activity on
> spark/sql/core/src/main/scala/org/apache/spark/sql/execution/datasources/PartitioningUtils.scala
> recently, so that seems related (especially the commits
> https://github.com/apache/spark/commit/7b5d9051cf91c099458d092a6705545899134b3b
> and
> https://github.com/apache/spark/commit/de289bf279e14e47859b5fbcd70e97b9d0759f14
> ).
> If I read correctly the tests added in those commits:
> -they don't seem to actually test the return value, only that it doesn't crash
> -they only test cases where the s3 path contain 1 key/value pair (which
> otherwise would catch the bug)
> This is problematic for us as we're trying to migrate all of our spark
> services to 1.6.0 and this bug is a real blocker. I know it's possible to
> force a 'union', but I'd rather not do that if the bug can be fixed.
> Any question, please shoot.
