Read timeout

Question

Hi,

I've successfully installed RapidMiner Server CE and added the remote repository to Rapidminer Studio.

Now I'm trying to upload a 70 MB tsv file to the remote repository using the Import CSV wizard, but it fails with SocketTimeoutException: Read timed out. According to some google research there is a setting "connection.timeout", which I've set to max int on both sides, but without luck.

Any ideas?

Thanks in advance!

This is clearly not the way to go then, if the upload process already takes more than 5 minutes. I noticed MySQL  behind taking even more time to import the rows and I have up to 2GB of data I want to use.

Is there any other way I can upload my data to the server? I noticed the upload function in the web interface, but that leaves me with a binary blob. Using the blob with any import operator results in an error, that the repository url "//_LOCAL/..." is malformed.

Thanks.

Hi,

you are getting a transaction timeout, i.e. your call is taking too long. What you can do for a quick fix is to increase the transaction timeout. Default is 300 seconds aka 5 minutes.
To see how this is done for RapidAnalytics (this does NOT work for RapidMiner Server), you can have a look here: click.

This is the log output. I guess the error has something to do with the last two lines.12:30:38,974 INFO  [de.rapidanalytics.web.servlet.AccessEntry] HTTP POST for location /home/admin/test, user admin, principal org.springframework.security.authentication.UsernamePasswordAuthenticationToken@a1f52353: Principal: org.springframework.security.core.userdetails.User@586034f: Username: admin; Password: [PROTECTED]; Enabled: true; AccountNonExpired: true; credentialsNonExpired: true; AccountNonLocked: true; Granted Authorities: admin,analyst,execute,report editor,report manager,report viewer,scheduler,service,users; Credentials: [PROTECTED]; Authenticated: true; Details: org.springframework.security.web.authentication.WebAuthenticationDetails@0: RemoteIpAddress: 141.100.73.57; SessionId: null; Granted Authorities: admin, analyst, execute, report editor, report manager, report viewer, scheduler, service, users
