Hi, question for snappy-java native library. I'm trying to figure out how to configure the native library.so dynamical loading to somewhere else than

/tmp/

. I have noticed that its probably happening within the s3-fs-presto plugin and my question is that how could I configure that context? It seems that

java.io.tmpdir

doesn't propagate correctly into the plugin.

You can pass at job submission time like this

export FLINK_ENV_JAVA_OPTS="-Dorg.xerial.snappy.tempdir=/path/to/your/custom/tempdir"
# then run your PyFlink script or command
python your_job_submission_script.py

Thanks! I'll try it out

sure otherwise maybe in flink-conf.yaml

env.java.opts: "-Dorg.xerial.snappy.tempdir=/path/to/your/custom/tempdir"

probably the latter as the loading happens after first checkpoint in taskmanagers

oh ok

It worked, thanks!

Glad it works!
