OutOfMemoryError on tFileInputJson

Anonymous — Sat, 16 Nov 2024 06:34:30 GMT

Hi,

I am in trouble with a tFileInputJson from an url.

I have the following error :

Exception in thread "main" java.lang.OutOfMemoryError: Java heap space
at java.util.Arrays.copyOf(Unknown Source)
at java.lang.AbstractStringBuilder.ensureCapacityInternal(Unknown Source)
at java.lang.AbstractStringBuilder.append(Unknown Source)

at p_flux1.api_grand_debat_0_1.API_Grand_Debat.main(API_Grand_Debat.java:2020)

The job is running for like 15min, the tFileInputJSon is stuck at Starting, and the error comes.

I dont find any solution, and i can't limit the data to dowload from the url Json doc.

Any help is welcome.

Regards,

Pierre

Hi,

A quick method is to increase the JVM parameters associated to your job to increase the memory.

You can change them at Run tab -> Advanced Settings

But it is just one side of memory management. You need to verify the flow why it is taking more memory. If you are using a tMap after reading the data from source, you need to use disk operation than full memory based operation.

Hi,

sorry for delay,

No it's not working, i have tried that trick already and i still get the same error, the file is really huge :

http://opendata.auth-6f31f706db6f4a24b55f42a6a79c5086.storage.sbg5.cloud.ovh.net/2019-01-31/LA_TRANSITION_ECOLOGIQUE.json

I guess i should use a trest component but i could not make it work.
