A bit too much copy-paste. I am not forced to critically think myself.

I encountered the following error in Lab3 but not Lab4. google528222_student@cluster-dataproc-m:~/lab2$ spark-submit wordcount.py Okay Google. 18/06/11 17:04:24 INFO org.spark_project.jetty.util.log: Logging initialized @2246ms 18/06/11 17:04:24 INFO org.spark_project.jetty.server.Server: jetty-9.3.z-SNAPSHOT 18/06/11 17:04:24 INFO org.spark_project.jetty.server.Server: Started @2347ms 18/06/11 17:04:24 INFO org.spark_project.jetty.server.AbstractConnector: Started ServerConnector@2689 069d{HTTP/1.1,[http/1.1]}{0.0.0.0:4040} 18/06/11 17:04:24 INFO com.google.cloud.hadoop.fs.gcs.GoogleHadoopFileSystemBase: GHFS version: 1.6.6 -hadoop2 18/06/11 17:04:26 INFO org.apache.hadoop.yarn.client.RMProxy: Connecting to ResourceManager at cluste r-dataproc-m/10.142.0.4:8032 18/06/11 17:04:28 WARN org.apache.hadoop.hdfs.DataStreamer: Caught exception java.lang.InterruptedException at java.lang.Object.wait(Native Method) at java.lang.Thread.join(Thread.java:1252) at java.lang.Thread.join(Thread.java:1326) at org.apache.hadoop.hdfs.DataStreamer.closeResponder(DataStreamer.java:973) at org.apache.hadoop.hdfs.DataStreamer.endBlock(DataStreamer.java:624) at org.apache.hadoop.hdfs.DataStreamer.run(DataStreamer.java:801) 18/06/11 17:04:28 INFO org.apache.hadoop.yarn.client.api.impl.YarnClientImpl: Submitted application a pplication_1528728154378_0003 18/06/11 17:04:36 WARN org.apache.spark.sql.execution.streaming.FileStreamSink: Error while looking f or metadata directory. ABOUT = 1 AGES = 2 ALL = 1 AND = 9 ANOTHER = 1 AS = 5 BACK. = 1 ... Also, the text for "Task 3: Delete the Dataproc cluster" is a bit funny: https://www.dropbox.com/s/iwb84r5x4ubldlz/Screenshot%202018-06-11%2014.17.39.png?dl=0 It reads: > There are quotas in Qwiklabs. If you do not delete the Dataproc cluster you will not run out of resources in the next lab.

O conteúdo é bom, mas há itens específicos que mereciam uma atenção maior. Ficou corrido demais em muitos momentos.
