[jira] [Commented] (PARQUET-124)
parquet.hadoop.ParquetOutputCommitter.commitJob() throws
parquet.io.ParquetEncodingException
[ https://issues.apache.org/jira/browse/PARQUET-124?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14192360#comment-14192360 ]
Ryan Blue commented on PARQUET-124:
-----------------------------------
Looks like the problem is that we're matching a URI against a path. The check should be `URI.getPath().startWith(dirPath)`.

> Key: PARQUET-124
> URL: https://issues.apache.org/jira/browse/PARQUET-124
> Project: Parquet
> Issue Type: Bug
> Components: parquet-mr
> Affects Versions: parquet-mr_1.6.0, 1.6.0rc2
> Reporter: Chris Albright
> Priority: Minor
>
> I'm running an example combining Avro, Spark and Parquet (https://github.com/massie/spark-parquet-example), and in the process of updating the library versions, am getting the warning below.
> The version of Parquet-Hadoop in the original example is 1.0.0. I am using 1.6.0rc3
> The ParquetFileWriter.mergeFooters(Path, List<Footer>) method is performing a check to ensure the footers are all for files in the output directory. The output directory is supplied by ParquetFileWriter.writeMetadataFile; in 1.0.0, the output path was converted to a fully qualified output path before the call to mergeFooters, but in 1.6.0rc[2,3] that conversion happens after the call to mergeFooters. Because of this, the check within merge footers is failing (the URI for the footers starts with file:, but not the URI for the root path does not)
> Here is the warning message and stacktrace.
