[SPARK-13667][SQL] Support for specifying custom date format for date and timestamp types at CSV datasource. by HyukjinKwon · Pull Request #11550 · apache/spark

HyukjinKwon · 2016-03-07T01:19:45Z

What changes were proposed in this pull request?

This PR adds the support to specify custom date format for DateType and TimestampType.

For TimestampType, this uses the given format to infer schema and also to convert the values
For DateType, this uses the given format to convert the values.
If the dateFormat is not given, then it works with DateTimeUtils.stringToTime() for backwords compatibility.
When it's given, then it uses SimpleDateFormat for parsing data.

In addition, IntegerType, DoubleType and LongType have a higher priority than TimestampType in type inference. This means even if the given format is yyyy or yyyy.MM, it will be inferred as IntegerType or DoubleType. Since it is type inference, I think it is okay to give such precedences.

In addition, I renamed csv.CSVInferSchema to csv.InferSchema as JSON datasource has json.InferSchema. Although they have the same names, I did this because I thought the parent package name can still differentiate each. Accordingly, the suite name was also changed from CSVInferSchemaSuite to InferSchemaSuite.

How was this patch tested?

unit tests are used and ./dev/run_tests for coding style tests.

@rxin There should be a conflict with #11315 which I think it's supposed to be merged (assuming from your comment).

I will resolve the conflict as soon as either this one or that one is merged.

@falaki Would you maybe review this please..?

@falaki Just let to know, I changed the name CSVInferSchema to InferSchema mainly for consistent names for CSV and JSON data source but maybe they might have to be CSVInferSchema and JSONInferSchema.

@HyukjinKwon I want to get this in for 2.0. Can you not do the renaming here? It's always super confusing when classes have the same name, even when they are in different packages. We are trying to move away from that. It will also make the patch much easier to review when the patch is more "precise".

HyukjinKwon · 2016-04-30T02:09:38Z

@rxin Thank you. I will change the name to the original.

HyukjinKwon · 2016-04-30T02:59:40Z

 nullable: Boolean = true,
- nullValue: String = ""): Any = {
+ nullValue: String = "",
+ dateFormat: SimpleDateFormat = null): Any = {


This will conflict with #11947 (this is making the last argument as a single option not for the multiple individual parameters like I did for infer() above).

rxin · 2016-04-30T03:08:36Z

Left some minor comments. LGTM otherwise.
