Description

Hi,

When i'm trying to dump a parquet file, i find the TCP connection leak in org.apache.parquet.tools.command.DumpCommand#dump :

 

...
ParquetFileReader freader = null;
if (showmd) {
    try {
        long group = 0;
        for (BlockMetaData block : blocks) {
            ...
            freader = new ParquetFileReader(
                conf, meta.getFileMetaData(), inpath, rblocks, columns);
            ...
            out.flushColumns();
        }
    } finally {
        if (freader != null) {
            freader.close();
        }
    }
}
