[jira] [Commented] (KAFKA-10604) The StreamsConfig.STATE_DIR_CONFIG's default value does not reflect the JVM parameter or OS-specific settings

    [ https://issues.apache.org/jira/browse/KAFKA-10604?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17212913#comment-17212913 ]

-------------------------------------

[~mjsax] Perhaps we need a KIP discussion for this issue, like [KIP-676|https://cwiki.apache.org/confluence/display/KAFKA/KIP-676%3A+Respect+logging+hierarchy]. Isn't it?

> I found this problem working for [KAFKA-10585|https://issues.apache.org/jira/browse/KAFKA-10585].
> The JVM's temporary directory location is different per OS, and JVM allows to change it with `java.io.tmpdir` system property. In Linux, it defaults to `/tmp`.
> The problem is the default value of StreamsConfig.STATE_DIR_CONFIG (`state.dir`) is fixed to `/tmp/kafka-streams`. For this reason, it does not change if the runs on OS other than Linux or the user specifies `java.io.tmpdir` system property.
> It should be `\{temp-directory}/kafka-streams`, not `/tmp/kafka-streams`.
