I am trying to use Apache Flume for saving tweets to my HDFS. I am currently using the Cloudera image with Hadoop and Flume. I was following the tutorial from Cloudera's blog, but I am not able to connect to the Twitter API.
I am getting following error:

I have copied my twitter API credentials to the flume.conf (I have tried in both on disc and web UI). I have also tried to regenerate them again and copy those new ones, but it didn't help me.
My pom.xml contains:
<dependency>
<groupId>org.twitter4j</groupId>
<artifactId>twitter4j-stream</artifactId>
<version>3.0.5</version>
</dependency>
That means that there shouldn't be the problem that is described here.
And I have also set the system time by command:
sudo ntpdate pool.ntp.org
Does anybody have some idea of what can possibly be wrong? Thank you very much in advance for any suggestions and help.
