Subject [jira] [Resolved] (IGNITE-7074) NPE when WAL path and WAL archive path are the same
Date Tue, 30 Jan 2018 07:40:00 GMT

Dmitriy Pavlov resolved IGNITE-7074.
------------------------------------
    Resolution: Fixed

Under https://issues.apache.org/jira/browse/IGNITE-7017 there was supported special WAL mode:
'no archiver'.
In case folders are equall then all files (both archive and work) are placed into this folder
instead of placing files first in work and then copying file from work to archive.

> Log here: https://gist.github.com/danellis/660054b5a7f0e83ae4dcac8c1516d2ca
> It appears that the WAL path and the WAL archive path cannot be set to the same directory.
When they are, instead of the invalid configuration being caught, a number of NPEs are thrown
as shown in the above log.
> Additionally, this constraint does not appear to be documented.
