# What is this directory?
|
||
|
|
|
||
|
|
* In order to perform certain functions, spark sometimes needs to write temporary data to the disk.
|
||
|
|
* Previously, a temporary directory provided by the operating system was used for this purpose.
|
||
|
|
* However, this proved to be unreliable in some circumstances, so spark now stores temporary data here instead!
|
||
|
|
|
||
|
|
spark will automatically cleanup the contents of this directory.
|
||
|
|
(but if for some reason it doesn't, if the server is stopped, you can freely delete any files ending in .tmp)
|
||
|
|
|
||
|
|
tl;dr: spark uses this folder to store some temporary data.
