QUESTION
I built the Apache Oozie 5.2.1 from the source code in my MacOS and currently having trouble running it. The ClassNotFoundException indicates a missing class org.apache.hadoop.conf.Configuration but it is available in both libext/ and the Hadoop file system.
I followed the 1st approach given here to copy Hadoop libraries to Oozie binary distro. https://oozie.apache.org/docs/5.2.1/DG_QuickStart.html
I downloaded Hadoop 2.6.0 distro and copied all the jars to libext before running Oozie in addition to other configs, etc as specified in the following blog.
https://www.trytechstuff.com/how-to-setup-apache-hadoop-2-6-0-version-single-node-on-ubuntu-mac/
This is how I installed Hadoop in MacOS. Hadoop 2.6.0 is working fine. http://zhongyaonan.com/hadoop-tutorial/setting-up-hadoop-2-6-on-mac-osx-yosemite.html
This looks pretty basic issue but could not find why the jar/class in libext is not loaded.
- OS: MacOS 10.14.6 (Mojave)
- JAVA: 1.8.0_191
- Hadoop: 2.6.0 (running in the Mac)
ANSWER
Answered 2021-May-09 at 23:25I was able to sort the above issue and few other ClassNotFoundException by copying the following jar files from extlib to lib. Both folder are in oozie_install/oozie-5.2.1.
- libext/hadoop-common-2.6.0.jar
- libext/commons-configuration-1.6.jar
- libext/hadoop-mapreduce-client-core-2.6.0.jar
- libext/hadoop-hdfs-2.6.0.jar
While I am not sure how many more jars need to be moved from libext to lib while I try to run an example workflow/job in oozie. This fix brought up Oozie web site at http://localhost:11000/oozie/
I am also not sure why Oozie doesn't load the libraries in the libext/ folder.
QUESTION
I used to use another proxy server library with C# to capture HTTP request, and it only has a AfterSessionComplete
event which fires after the whole request/response action has all finished, and you can get the the host, path and query, request and response body all from the event argument. However that library stopped maintenancing sometime ago so I am considering switching to Titanium-Web-Proxy, and seems like it has a AfterResponse
event. Here is what I used to test:
ANSWER
Answered 2020-Oct-02 at 14:21In Titanium, the AfterResponse event marks a moment when the response was sent to the browser (and is no longer available). So to read the response body, you need to attach to the BeforeResponse event. Additionally, as you observed, you can't access the request body in the* Response events. One option to overcome this limitation is to use the UserData property and, in the BeforeRequest event, save all the data from the request body that you may later need. The example code below shows how to do that:

QUESTION
I created a Hadoop cluster with 1 master and 2 slaves. All of the services are running in nodes. Datanode and Nodemanager are active on slave1 and slave2. Namenode, Datanode, Nodemanager, ResourceManager, and SecondaryNameNode are active on the master. But the Web UI of NameNode (localhost:50070
) in part of Live nodes shows 1 node (master) and the web UI of yarn shows 1 active node.
The following works are done:
- Disable firewall.
- Password-less ssh connection between all of the nodes.
- Hostname configuration.
- Transfer Hadoop config files from master to slaves.
how to solve this problem?

...ANSWER
Answered 2018-Jun-12 at 08:51I found the solution. By checking the log, I understood the problem there is because of the wrong definition of hostnames. They should be defined as FQDN. And also to remove the error:
Retrying connect to server: localhost/127.0.0.1:9000
should remove the line with 127.0.1.1 address from all hosts, Otherwise, it's only listening on that local address, not the external one. As blew:

I am trying to write a test to pass valid and invalid proxy details. I have written a Pytest fixture which will do request and return the response. But my problem is that I would like to send invalid and valid proxy details during fixture. Can someone correct me whether this approach is correct or suggest me with the valid approach, I am new to Pytests. I have tried the following way.
...ANSWER
Answered 2018-Nov-18 at 13:52You need to parameterize your test cases and not your fixture. Also, this is not a use case for using fixtures. So, instead here's how you should handle it:
