Issue: (at Line: 430)
In the example of writing a local file to a table (public long writeFileToTable(String datasetName, String tableName, Path csvPath, String location) throws IOException, InterruptedException, TimeoutException), TableDataWriteChannel needs to be closed.

Solution: replace line 428-430 with the following code snippet:
try (OutputStream stream = Channels.newOutputStream(writer)) { Files.copy(csvPath, stream); } finally { writer.close(); }
