Shivam Dalmia commented on PARQUET-1080:
----------------------------------------
Hi [~hyukjin.kwon] thanks for your comment;I will raise it with spark, as you
mentioned.
> Empty Parquet Files created as a result of spark jobs fail when read
> --------------------------------------------------------------------
>
> Key: PARQUET-1080
> URL: https://issues.apache.org/jira/browse/PARQUET-1080
> Project: Parquet
> Issue Type: Bug
> Components: parquet-format
> Reporter: Shivam Dalmia
> Priority: Minor
>
> I have faced an issue intermittently with certain spark jobs writing parquet
> files which apparently succeed but the written .parquet directory in HDFS is
> an empty directory (with no _SUCCESS and _metadata parts, even).
> Surprisingly, no errors are thrown from spark dataframe writer.
> However, when attempting to read this written file, spark throws the error:
> {{Unable to infer schema for Parquet. It must be specified manually}}
