[jira] [Commented] (SOLR-11786) Allow setting java.io.tmpdir from an environment variable

    [ https://issues.apache.org/jira/browse/SOLR-11786?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16299062#comment-16299062 ] 

Shawn Heisey commented on SOLR-11786:
-------------------------------------

The patch will need to be careful to do the right thing if the variable is not defined.  The information I have says that Java hardcodes the value to /tmp when it is not defined, except on an OS like Windows, where it asks the OS where the temp directory is.

> The Java temporary directory (/tmp by default on POSIX systems) may be mounted to a location with limited space.  This has become a problem for some users who build large suggester dictionaries.
> The solr start scripts should offer a way to configure the java.io.tmpdir system property from an environment variable that may be set by the include script.
> Initial idea for the variable name: JAVA_TMP_DIR or maybe SOLR_JAVA_TMP_DIR
