You can get the file InputStream via BlobKey(String blobKey) as constructor parameter to BlobstoreInputStream(BlobKey blobKey).

For example:

BlobstoreInputStream is = new BlobstoreInputStream(new BlobKey("YOU_BLOB_KEY"));

For parsing CSV file, you can consider use opencsv's CSVReader.

For example:

CSVReader csvReader = new CSVReader(new InputStreamReader(is));
List<String[]> rows = csvReader.readAll();
