Re: Configuring IoTDB when run programatically
Hi Chris,
When I was looking into issue [1], I discovered that IoTDB failed to load iotdb-engine.properties file on Windows.
It looks like in IoTDBDescriptor getPropsUrl() line 127, Windows file path like "D:\\path" will not be accepted by URL constructor, thus an exception thrown.
I've submitted a PR [2] for this case. Would you please take a look and check this PR? I suppose it is the same cause with your Windows VM failure.
Also, I haven't got a SprintBoot environment to test URLs like "classpath:path". It would be great if you could test the "classpath" scenario on your machine, in case it made some regression. :D

Thanks,

Hi Chris,

Sorry, I made that change to fix the file loading bug in Windows and
ignored your original purpose.[1]
> // If the url doesn't start with "file:" or "classpath:" it's
provided as a normal path.
// So we need to add it to make it a real URL.
if(!urlString.startsWith("file:") &&
!urlString.startsWith("classpath:")) {
urlString = "file:" + urlString;
}
I agree with the idea you proposed.

Re: Configuring IoTDB when run programatically
Posted by Christofer Dutz <ch...@c-ware.de>.
Hi Wie,
Your proposed change would remove the ability to load the config from classpath as you can't reference a classpath resource with a File.
However we could get an url from a File ... perhaps that's a way to go. In general perhaps using a File object and accessing that objects: "new File("").toURI().toURL()" instead would allow both.
I also noticed my PR wasn't merged as I submitted it. By changing:
// If the url doesn't contain a ":" it's provided as a normal path.
// So we need to add the prefix "file:" to make it a real URL.
if(!urlString.contains(":")) {
urlString = "file:" + urlString;
}
To:
// If the url doesn't start with "file:" it's provided as a normal path.
// So we need to add it to make it a real URL.
if(!urlString.startsWith("file:")) {
urlString = "file:" + urlString;
}
Again the ability to use a classpath resource is eliminated as a classpath resource is referenced via:
classpath:/path/to/resource.properties
Instead of:
file:/path/to/resource.properties
But I can imaging that particularly in combination with windows systems it might be better to use:
// If the url doesn't start with "file:" or "classpath:" it's provided as a normal path.
// So we need to add it to make it a real URL.
if(!urlString.startsWith("file:") && !urlString.startsWith("classpath:")) {
urlString = "file:" + urlString;
}
This should avoid the problem.
