--------------------------------------
Component/s: reader-core
> spark datasource load path format is confused for snapshot and increment read
> mode
> ----------------------------------------------------------------------------------
>
> Key: HUDI-1307
> URL: https://issues.apache.org/jira/browse/HUDI-1307
> Project: Apache Hudi
> Issue Type: Improvement
> Components: reader-core, spark
> Reporter: liwei
> Assignee: liwei
> Priority: Critical
> Labels: query-eng, sev:high, user-support-issues
>
> as spark datasource read hudi table
> 1、snapshot mode
> {code:java}
> val readHudi = spark.read.format("org.apache.hudi").load(basePath + "/*");
> should add "/*" ,otherwise will fail, because in
> org.apache.hudi.DefaultSource.
> createRelation() will use fs.globStatus(). if do not have "/*" will not get
> .hoodie and default dir
> val globPaths = HoodieSparkUtils.checkAndGlobPathIfNecessary(allPaths,
> fs){code}
>
> 2、increment mode
> both basePath and basePath + "/*" is ok.This is because in
> org.apache.hudi.DefaultSource
> DataSourceUtils.getTablePath can support both the two format.
> {code:java}
> val incViewDF = spark.read.format("org.apache.hudi").
> option(QUERY_TYPE_OPT_KEY, QUERY_TYPE_INCREMENTAL_OPT_VAL).
> option(BEGIN_INSTANTTIME_OPT_KEY, beginTime).
> option(END_INSTANTTIME_OPT_KEY, endTime).
> load(basePath){code}
>
> {code:java}
> val incViewDF = spark.read.format("org.apache.hudi").
> option(QUERY_TYPE_OPT_KEY, QUERY_TYPE_INCREMENTAL_OPT_VAL).
> option(BEGIN_INSTANTTIME_OPT_KEY, beginTime).
> option(END_INSTANTTIME_OPT_KEY, endTime).
> load(basePath + "/*")
> {code}
>
> as increment mode and snapshot mode not coincide, user will confuse .Also
> load use basepath +"/*" *or "/***/*"* is confuse. I know this is to support
> partition.
> but i think this api will more clear for user
>
> {code:java}
> partition = "year = '2019'"
> spark.read .format("hudi") .load(path) .where(partition) {code}
>
