Example 47 with FileAlreadyExistsException

use of org.apache.hadoop.fs.FileAlreadyExistsException in project ignite by apache.

Example 48 with FileAlreadyExistsException

use of org.apache.hadoop.fs.FileAlreadyExistsException in project stocator by SparkTC.

the class ObjectStoreFileSystem method mkdirs.

/**
 * {@inheritDoc}
 *
 * When path is of the form schema://dataroot.provider/objectname/_temporary/0
 * it is assumed that new job started to write it's data.
 * In this case we create an empty object schema://dataroot.provider/objectname
 * that will later be used to identify objects that were created by Spark.
 * This is needed for fault tolerance coverage to identify data that was created
 * by failed jobs or tasks.
 * dataroot/object created as a 0 size object with type application/directory
