I guess you check this from the host where FSCrawler is also running, right?

What is your FSCrawler config for the job?
Could you start FSCrawler with the --debug option?

How do you launch it?

Hi,
It is showing

Could you answer to all my questions please?

vikram_singh · January 11, 2021, 12:03pm

Hi,
Above logs was after --debug.
Yes you were right, issue was due to location of fscrawler config path.
Now it is setup correctly and working with sample txt file.

I want to crawl sharepoint files data from fscrawler(it is setup on docker) is it possible or any elasticsearch plugin for sharepoint file crawl.

dadoonet · January 11, 2021, 12:17pm

If you can mount the sharepoint drive, then FSCrawler can probably index the content.
Otherwise, I'd recommend looking at workplace search which has a lot of connectors.

vikram_singh · January 12, 2021, 5:52am

Hi,
Workplace search starts with open source licence or need a minimum elastic licence subscription.
Can it work with elastic basic licence.

dadoonet · January 12, 2021, 6:11am

It starts from basic license.

vikram_singh · January 22, 2021, 6:30pm

Hi,
issue on fscrawler side.
It was working correctly earlier, now I creating mysecondjob and it is start giving error.

dadoonet · January 22, 2021, 7:23pm

Please don't post images of text as they are hard to read, may not display correctly for everyone, and are not searchable.

Instead, paste the text and format it with </> icon or pairs of triple backticks (```), and check the preview window to make sure it's properly formatted before posting it. This makes it more likely that your question will receive a useful answer.

It would be great if you could update your post to solve this.

Please provide the full logs. And run it with --trace option please.

vikram_singh · January 22, 2021, 7:42pm

Hi,
below log is after --trace.

Hi David,
I got your suggestion for a proper format of posting logs.

And for providing the full logs, below are the full logs from fscrawler starting point.

dadoonet · January 27, 2021, 11:41am

I see. You are using the FSCrawler Docker image which is probably an old one.

Any chance you could either rebuild a new version by yourself? There's a pending PR to have a proper docker image but it's not yet there.

Or don't use that docker image but a normal installation?

vikram_singh · January 27, 2021, 12:08pm

Hi,
my complete environment is on docker. Any FSCrawler Docker latest image which support elasticsearch version 7.10.

dadoonet · January 27, 2021, 2:25pm

I think this image has been built last time a year ago: https://hub.docker.com/r/toto1310/fscrawler

Mine is also one year old: https://hub.docker.com/repository/docker/dadoonet/fscrawler

But as I said, there is a work pending here:

It does not work yet sadly.
If you are familiar with Docker, and want to help there, please do
