> Key: IMPALA-10780
> URL: https://issues.apache.org/jira/browse/IMPALA-10780
> Project: IMPALA
> Issue Type: Improvement
> Reporter: Yong Yang
> Priority: Major
>
> Currently, the filesystem of the metadata path is used to check the data file, that is blocking the following scenario:
> # metadata is on hdfs
> # data is on s3a or other object store.
>
> Following code in FeIcebergTable.Utils fails this combination:
> private static HdfsPartition.FileDescriptor getFileDescriptor(Path fileLoc,
> Path tableLoc, ListMap<TNetworkAddress> hostIndex) throws IOException
> {
> FileSystem fs = FileSystemUtil.getFileSystemForPath(tableLoc); FileStatus fileStatus = fs.getFileStatus(fileLoc);
> return getFileDescriptor(fs, tableLoc, fileStatus, hostIndex);
> }
