cassandra-stress: URI is not absolute error - cassandra-2.0

I am trying to run cassandra-stress from a bash script:
HUB_STATUS_YAML="~/some-path/hub_errors.yaml"
COMMAND="cassandra-stress user profile=${HUB_STATUS_YAML} ops(insert=1)"
echo About to run $COMMAND
$COMMAND
I end up with the following error: "URI is not absolute".

axelcdv's comment concurred with my experience of this problem.
Make sure you spell the file name correctly.
I'm taking DataStax training atm and encountered the same error.
I was spelling the cqlstress.yaml as csqlstress.yaml the "URI is not absolute" error.

Terraform GCP Instance Metadata Startup Script Issue

I've been working with Terraform, v0.15.4, for a few weeks now, and have gotten to grips with most of the lingo. I'm currently trying to create a cluster of RHEL 7 instances dynamically on GCP, and have, for the most part, got it to run okay.
I'm at the point of deploying an instance with certain metadata passed along to it for use in scripts built into the machine image for configuration thereafter. This metadata is typically just passed via an echo into a text file, which the scripts then pickup as required.
It's... very simple. Echo "STUFF" > file... Alas, I am hitting the same issue OVER AND OVER and it's driving me INSANE. I've Google'd around for ages, but all I can find is examples of the exact thing that I'm doing, the only difference is that theirs works, mine doesn't... So hopefully I can get some help here.
My 'makes it half-way' code is as follows:
resource "google_compute_instance" "GP_Master_Node" {
...
metadata_startup_script = <<-EOF
echo "hello
you" > /test.txt
echo "help
me" > /test2.txt
EOF
Now the instance with this does create successfully, although when I look onto the instance, I get one file called ' /test.txt? ' (or if I 'ls' the file, it shows as ' /test.txt^M ') and no second file.. I can run any command instead of echo, and whilst the first finishes, the second+ does not. Why?? What on earth is causing that??
The following code I found also, but it doesn't work for me at all, with the error, 'Blocks of type "metadata" are not expected here.'
resource "google_compute_instance" "GP_Master_Node" {
...
metadata {
startup-script = "echo test > /test.txt"
}
Okaaaaay! Simple answer for a, in hindsight, silly question (sort of). The file was somehow formmated in DOS, meaning the script required a line continuation character to run correctly (specifically \ at the end of each individual command). Code as follows:
resource "google_compute_instance" "GP_Master_Node" {
...
metadata_startup_script = <<-EOF
echo "hello
you" > /test.txt \
echo "help
me" > /test2.txt \
echo "example1" > /test3.txt \
echo "and so on..." > /final.txt
EOF
However, what also fixed my issue was just 'refreshing' the file (probably a word for this, I don't know). I created a brand new file using touch, 'more'd the original file contents to screen, and then copy pasted them into the new one. On save, it is no longer DOS, as expected, and then when I run terraform the code runs as expected without requiring the line continuation characters at the end of commands.
Thank you to commentors for the help :)

How can I handle the error in load_svmlight_file?

when I run this code in mac:
x_train, y_train = load_svmlight_file("mq2008.train")
I get this error in bash:
-bash: syntax error near unexpected token `('
and if I run it in shell, I face this error:
NameError: name 'load_svmlight_file' is not defined
How can I solve this problem?
Welcome to StackOverflow!
IMO, you have a Python code and trying to replicate its output. If so, you should first load all Python-related imports first. This is what it means to NameError here, Python interpreter is not able to understand what it is, because this function is not part of its existing definitions it has.
If I may suggest, please spend some time to get the hands-on-learning of Python.

Generate custom error message from makefile with WDK build tools

I'm compiling a driver using build.exe from the Windows Driver Kit.
The system which builds the drivers needs to have a specific environment variable set. If not, I want build to fail with a custom error message.
Does anyone have an idea on how to do that?
I already tried to output a message to stderr by adding this test to makefile.inc:
all:
echo My Custom Error 1>&2
But the output doesn't show up and the build process doesn't fail. I do know that the all target is executed, as I have tested this by redirecting the output to a file.
Something like this:
! IF "$(YOUR_ENV_VAR)"=="Your condition"
! message BUILDMSG: Your message
! ELSE
! INCLUDE $(NTMAKEENV)\makefile.def
! ENDIF
Finally, I've found a solution.
F.e.: if you add this to the makefile.inc, you will force it to fail:
all:
echo fatal error : Whatever error message you like
Please use the exact format (and lower-casing) for the string "fatal error x", where x can be replaced with the message you want.

Oracle Forms - Host Command - Return Error Code

Within a Oracle Forms trigger I am using the host command to make a directory on the file server. An example of this part of my code is below:
HOST ('mkdir'||:GLOBAL.DIRECTORY_PATH||'\FERTILIZER\'||ADDY);
I need to have the error code returned to me if the directory is not created on the server. Any suggestions of the code I need to add?
Thank you.
FORM_SUCCESS will return FALSE if the command fails for any reason (unless you're on Windows 95 in which case it will still return TRUE).
HOST('...');
IF NOT FORM_SUCCESS THEN
MESSAGE('something went wrong');
END IF;
If you are looking for the actual OS level error code, then you are out of luck. The aforementioned answer from Jeffrey Kemp
is the best you will get.
If you are having failures, keep in mind that the HOST built-in runs on the machine that actually runs the form (normally the application server). So, your command must be valid for the particular OS of the application server.
Also, and you may have figured this out already, in your example, 'mkdir'||:GLOBAL.DIRECTORY_PATH||'\FERTILIZER\'||ADDY
could result in your command having no space between the command - mkdir and the string, resulting in a failed command.
You still can get the error message by using this statement HOST(vCommand || ' > error.txt');

VBScript Expected End 800A03F6

I am getting this error while trying to run a VBScript (note this is not in a web environment - just running a VBScript on Windows):
Line: [Last line]
Error: Expected 'End'
Code: 800A03F4
Source: Microsoft VBScript compilation error
I think it is an If statement that is not closed correctly with an "End If," but I've gone through every instance of "If" in the code and cannot find the error. Any tips or tools that could help me figure out where/why this error is occurring?
There was an "Else If" - there should be no space there: "Elseif"

Hopefully this will help someone out in the future.
In VBScript If is not the only token that requires an End. Also look for Function's and Sub's without their appropriate end statements.
