Could you add tests? Probably, you could insert some data then check if the data compressed by listing up files in temp dir?

I have added the test. However, all of my local use cases do not work properly, so I'm not sure if the new use case will pass, but I will always be concerned.

@gatorsmile Is it worth fixing this? If so, could you trigger tests?

@maropu @fjh100456 If the issue is true, we should fix it for sure. However, the PR description must be wrong. If this issue exists, it should be applicable to both partitioned and non-partitioned ORC/Parquet tables. cc @dongjoon-hyun I think you might be interested in ORC side.

fjh100456 · 2017-09-15T08:17:25Z

@gatorsmile

Non-partitioned tables do not have this problem, 'spark.sql.parquet.compression.codec' can take effect normally, because the process of writing data differs from that of a partitioned table.
ORC does not have a configuration similar to 'spark. sql.* ', but can only use ' orc. compress ' which may not be a spark configuration.

fjh100456 · 2017-09-16T11:33:41Z

@dongjoon-hyun

A problem has been encountered, There are two ways to specify the compression format:

CREATE TABLE Test(id int) STORED AS ORC TBLPROPERTIES ('orc.compress'='SNAPPY');
set orc.compress=ZLIB;

If the table already has been specified a compression format when it was created, and then specified another compression format by setting 'orc.compress', the latter will take effect.

So whether the spark side should not have the default value, we can distinguish by 'undefined'; or discard this change, and explain in the document that 'spark.sql.parquet.compression.codec' for partitioned tables does not take effect, and 'spark.sql.orc.compression.codec ' is not valid for hive tables. Or your other better solution.

gatorsmile · 2017-09-17T06:10:05Z

I see. If you set spark.sql.hive.convertMetastoreParquet to false, you will also hit the issue for non-partitioned table.

Please update your PR description and title.

gatorsmile · 2017-09-17T06:11:55Z

 val tmpLocation = getExternalTmpPath(sparkSession, hadoopConf, tableLocation)

Move the whole logics into saveAsHiveFile, which is being shared by InsertIntoHiveDirCommand and InsertIntoHiveTable. Both need these logics.

+ Option((ParquetOutputFormat.COMPRESSION, compressionCodec))
+ case formatName if formatName.endsWith("orcoutputformat") =>
+ val compressionCodec = new OrcOptions(tableInfo.getProperties.asScala.toMap,
+ sqlConf).compressionCodec


Also update OrcOptions's compressionCodec to compressionCodecClassName

The compressionCodec is used in several places, do you mean I should fix them all?

Yeah. Just to make it consistent

gatorsmile · 2017-12-22T07:56:28Z


 class InsertSuite extends QueryTest with TestHiveSingleton with BeforeAndAfter
- with SQLTestUtils {
+ with ParquetTest {


This is the insert suite. We are unable to do this.
Could you create a separate suite in the current package org.apache.spark.sql.hive? The suite name can be CompressionCodecSuite

Please also check whether the compression takes an effect? Compare the size whether is smaller than the original size without compressions?

Ok, I will do it.

Seems compressed table does not always be smaller than uncompressed tables.
SNAPPY Compression size may be bigger than non-compression size when the amount of data is not big. So I'd like to check the size not equal when compression are different.

Fine to me. Thanks!

gatorsmile · 2017-12-22T07:59:18Z

+ tableInfo.getOutputFileFormatClassName.toLowerCase match {
+ case formatName if formatName.endsWith("parquetoutputformat") =>
+ val compressionCodec = new ParquetOptions(tableInfo.getProperties.asScala.toMap,
+ sqlConf).compressionCodecClassName


We normally do not split the code like this. We like the following way:
valtableProps= tableInfo.getProperties.asScala.toMap tableInfo.getOutputFileFormatClassName.toLowerCase match { case formatName if formatName.endsWith("parquetoutputformat") =>valcompressionCodec=newParquetOptions(tableProps, sqlConf).compressionCodecClassName Option((ParquetOutputFormat.COMPRESSION, compressionCodec)) ...

Yes it looks better, I will change it.

+import scala.collection.JavaConverters._
+
+import org.apache.hadoop.hive.ql.plan.{FileSinkDesc, TableDesc}


FileSinkDesc is still needed?

I will remove it.

+ val parquetCompressionConf = parameters.get(ParquetOutputFormat.COMPRESSION)
+ val codecName = parameters
+ .get("compression")
+ .orElse(parquetCompressionConf)


Is this new? Do we support parquet.compression before this PR?

Yes it's new. I guess PartitionOptions did not used when writing hive table before, because it's invisible for hive. I changeed it to public.

Could we keep the old behavior? We could add it later? We do not want to mix multiple issues in the same PR?

If so, parquet's table-level compression may be overwrited in this PR, and it may not be what we want.
Shall I fix it first in another PR?

Yeah, we can submit a separate PR for that issue. The behavior change needs to be documented in SparkSQL doc.

gatorsmile · 2017-12-22T08:08:28Z

+ HiveOptions.getHiveWriteCompression(fileSinkConf.getTableInfo, sparkSession.sessionState.conf)
+ .foreach{ case (compression, codec) =>
+ hadoopConf.set(compression, codec)
+ }


.foreach { case (compression, codec) => hadoopConf.set(compression, codec) }

gatorsmile · 2017-12-22T08:14:54Z

Could you also add another test scenario? For the existing Hive tables (created by Hive), does our Spark respect it? Do we use the existing compression configuration?

fjh100456 · 2017-12-23T07:49:26Z

@gatorsmile
I'd test manully. When table-level compression not configured, it always take the session level compression, and ignore the existing file compression. Seems like a bug, however, table files with multiple compressions do not affect the reading and writing.
Is it ok to add a test to check reading and writing when there are multiple conpressions in the existing table files?

gatorsmile · 2017-12-23T07:52:25Z

What are multiple compressions?

fjh100456 · 2017-12-23T08:16:12Z

I mean sevral files with different compressioncodcs under the same table directory, like below:

It were generated by changing the configation before inserting, like the follow scala code:

 spark.sql("set spark.sql.parquet.compression.codec=uncompressed")
spark.sql("insert into table temp_parquet_b select * from datasource_table")
spark.sql("set spark.sql.parquet.compression.codec=snappy")
spark.sql("insert into table temp_parquet_b select * from datasource_table")
spark.sql("set spark.sql.parquet.compression.codec=gzip")
spark.sql("insert into table temp_parquet_b select * from datasource_table")

Could you reduce it to a smaller number? The test cases are very slow to run.
