Marius Soutier updated SPARK-6648:
----------------------------------
Description:
When reading from multiple parquet files (via
sqlContext.parquetFile(/path/1.parquet,/path/2.parquet), and one of the parquet
files is being overwritten using a different coalesce (e.g. one only contains
part-r-1.parquet, the other also part-r-2.parquet, part-r-3.parquet), the
reading fails with:
ERROR c.w.r.websocket.ParquetReader efault-dispatcher-63 : Failed reading
parquet file
java.lang.IllegalArgumentException: Could not find Parquet metadata at path
<path>

I haven't tested with Spark 1.3 yet but will report back after upgrading to
1.3.1 (as soon as it's released).
