training = spark.read.format("libsvm").load("sample_linear_regression_data.txt")

i had the same problem probably you have a space somewhere in the name of your folder
It worked for me when I copied the dataset to the directory where my notebook is present. However, it does not work when I set a different filepath and try to load from that filepath

I create an external table in Hive with partitions and then try to populate it from the existing table, however, I get the following exceptions:

According to the internet these exceptions occur when datanode can't communicate with namenode or when you are running low on memory, but in my case everything is fine. I have already tried formatting my namenode and datanode as well. What else could be the issue?
https://wiki.apache.org/hadoop/CouldOnlyBeReplicatedTo I've also read this. And it didn't help me.
I am running on tez. this works:
insert into table browserdatapart partition(cityid) select UserAgent,cityid from browserdata limit 100;
And this fails with the exception I provided:
insert into table browserdatapart partition(cityid) select UserAgent,cityid from browserdata;
SET hive.exec.max.dynamic.partitions=100000;
SET hive.exec.max.dynamic.partitions.pernode=100000;
Setting the above parameters solved it for me. I guess hive was not able to replicate data to those partitions that show up in the exception, because there were more than the maximum (which is 224 in the case of my dataset).

Some person got the same problem as well:
https://community.cloudera.com/t5/Web-UI-Hue-Beeswax/HUE-and-Presto-Integration-Error-on-Page-Load/td-p/62353
I am hoping for your help!
check this issue on GitHub: JDBC connector only supports Teradata.
seems it's been fixed in version 4.3.0;
you could try using [librdbms] section also

zip_pandas = zip_table.toPandas()

Other Spark Dataframes are successfully able to call toPandas() while others such as this return the same error.
The file in question is not particularly big and should be able to fit in the driver no problem. Also, I know it may be better to just load it into Pandas directly and not convert from Spark, but there is further logic in the code that requires both Spark/Pandas dataframes (and a later re-architecture of this work will address this issue).
I am getting following exception if I place dummy array. eg, in Security/RelatedSecurities/RelatedSecurities. I tried to build a json schema from the response where it is empty. But if I use json validator it gives sytax error "array must have atleast one element". So I used the dummy array elements. After that I do not get syntax error but the validation fails with following error. Actual not matching with expected.
I will be happy to share the response and json schema if anyone is willing to help.

In the mentioned line of code is just this:
return new JDialog();
I guess is related to the Jenkins environment not having something enabled. How can this get fixed?
I can disable that test, but why should I?
You need to run your build inside a virtual (headless) graphical environment, using XVNC (or XVFB). See wiki.cloudbees.com/bin/view/DEV/Testing+GUI+applications.
Edit 20/01/2016:
The link above no longer takes you to a page with relevant information. This link shows the page as it was at the time: https://web.archive.org/web/20120717015714/http://wiki.cloudbees.com/bin/view/DEV/Testing+GUI+applications
You might also consider refactoring your code a bit to use a mock service so that tests do not need to load AWT. This will likely make tests faster and more reliable, as well as minimizing the chance that they will fail in novel environments such as a CI server.
