lb web-client export always using /tmp directory

Question

In my lb-web-server.config file I have set the following:

[handler:delimited-file]
classname = com.logicblox.bloxweb.delim.DelimitedFileHandler
tmpdir = /my/temp/dir

When I run an export with lb web-client export --no-compress --output /some/dir/myfile.csv http://service-uri a temporary file is created in /my/temp/dir, but several files are also written to /tmp:

-rw-r--r--.  1 root       root         109M Oct  9 12:13 tmp21498_2316_XXYMElJ4
-rw-r--r--.  1 root       root         106M Oct  9 12:13 tmp21498_2317_XXTHg8fE
-rw-r--r--.  1 root       root         114M Oct  9 12:15 tmp21498_2318_XXQhuWvW
-rw-r--r--.  1 root       root         106M Oct  9 12:15 tmp21498_2319_XX7KbYmo

When the combined size of these temp files exceeds the available space on /tmp, the export fails.

Am I missing an additional setting in lb-web-server.config which would cause these files to be written to the correct location?

Answer 1

I think you can avoid storing these temp files under /tmp by setting the LB_TEMPDIR environment variable to another directory.

Answer 2

It would appear the runtime is using "generic" temporary files, whose location is controlled by the environment variable LB_TEMPDIR (defaulting to /tmp). I'm not aware of any config file setting to control it, unfortunately.

I will file a bug.
