> Hadoop file system config should be effective in data source options
> ---------------------------------------------------------------------
>
> Key: SPARK-31935
> URL: https://issues.apache.org/jira/browse/SPARK-31935
> Project: Spark
> Issue Type: Bug
> Components: SQL
> Affects Versions: 2.4.6, 3.0.0
> Reporter: Gengliang Wang
> Assignee: Gengliang Wang
> Priority: Major
> Fix For: 2.4.7, 3.0.1, 3.1.0
>
>
> Data source options should be propagated into the hadoop configuration of method `checkAndGlobPathIfNecessary`
> From org.apache.hadoop.fs.FileSystem.java:
> {code:java}
> public static FileSystem get(URI uri, Configuration conf) throws IOException {
> String scheme = uri.getScheme();
> String authority = uri.getAuthority();
> if (scheme == null && authority == null) { // use default FS
> return get(conf);
> }
> if (scheme != null && authority == null) { // no authority
> URI defaultUri = getDefaultUri(conf);
> if (scheme.equals(defaultUri.getScheme()) // if scheme matches default
> && defaultUri.getAuthority() != null) { // & default has authority
> return get(defaultUri, conf); // return default
> }
> }
>
> String disableCacheName = String.format("fs.%s.impl.disable.cache", scheme);
> if (conf.getBoolean(disableCacheName, false)) {
> return createFileSystem(uri, conf);
> }
> return CACHE.get(uri, conf);
> }
> {code}
> With this, we can specify URI schema and authority related configurations for scanning file systems.
