Subject Re: How to change tmp directory

Solr is probably simply using Java's temp directory, which you can redefine 
by setting the system property on the java command line or 
using a system-specific environment variable.

Subject: How to change tmp directory

Hello all,

I came about an odd issue today when I wanted to add ca. 7M documents to my 
Solr index: I got a SolrServerException telling me "No space left on 
device". I had a look at the directory Solr (and its index) is installed in 
and there is plenty space (~300GB).
I then noticed a file named "upload_457ee97b_1385125274b__8000_00000005.tmp" 
had taken up all space of the machine's /tmp directory. The partition 
holding the /tmp directory only has around 1GB of space and this file 
already took nearly 800MB. I had a look at it and I realized that the file 
contained the data I was adding to Solr in an XML format.

Is there a possibility to change the temporary directory for this action?

I use an Iterator<SolrInputDocument> with the HttpSolrServer's add(Iterator) 
method for performance. So I can't just do commits from time to time.

Best regards,
