Udit Joshi updated PARQUET-1587:
--------------------------------
Description:
*Problem :-*
I am trying to create the object of {color:#d04437}ParquetWriter{color} class
which accepts the argument (OutputFile, Mode, WriteSupport,
CompressionCodecName, int, boolean, Configuration, int, ParquetProperties). But
this constructor has default access modifier. I can't able to access it.
I also used {color:#d04437}ParquetFileWriter{color} class but it doesn't show
any group support.
*Gradle dependency*
{quote}compile group: 'org.apache.parquet', name: 'parquet-hadoop', version:
'1.10.1'
{quote}
*Is there any way to writer parquet file into Hadoop with GroupSupport?*
*ParquetWriter*
*!image-2019-05-31-10-41-45-674.png!*
ParquetFileWriter
{code:java}
ParquetFileWriter writer = new
ParquetFileWriter(HadoopOutputFile.fromPath(writePathFile, configuration),
schema, Mode.CREATE, DEFAULT_BLOCK_SIZE, MAX_PADDING_SIZE_DEFAULT) ;
writer.start();{code}
It creates the file in parquet file in hadoop but can't facilates to write
List of Groups in parquet file
ExampleParquetWriter
{code:java}
ParquetWriter<Group> writer =
ExampleParquetWriter.builder(writePathFile).withConf(configuration).withType(getSchema()).build();
System.out.println("Number of groups to write:" + groups.size());
for (Group g : groups) {
writer.write(g);
} {code}
Doesn't support for writing in hadoop
