Hi Arvid, Thank you for the suggestion.
Indeed, the specified setting was commented out in the Flink configuration (flink-conf.yaml). # io.tmp.dirs: /tmp Is there a fallback (e.g. /tmp) if io.tmp.dirs and System.getProperty("java.io.tmpdir") are both not set? Will configure this setting to a valid value as suggested. Kind regards, Vinaya -- Sent from: http://apache-flink-user-mailing-list-archive.2336050.n4.nabble.com/
