Ivan Rakov commented on IGNITE-8456:
------------------------------------
[~SomeFire], I've looked through your changes.
I think, current message is not informative enough. My suggestions:
1. Use actual value of java.io.tmpdir property in warning message instead of
its name.
2. Except for setting IGNITE_HOME, it's possible to change location of
persistence folders with data storage configuration (see
DataStorageConfiguration#walPath, DataStorageConfiguration#walArchivePath,
DataStorageConfiguration#storagePath properties). This option should be
mentioned in warning message as well.
> Print warning if IGNITE_HOME & WORK and persistentStoreDir is not set, but
> persistence enabled

> Project: Ignite
> Issue Type: Improvement
> Components: persistence
> Reporter: Dmitriy Pavlov

> Fix For: 2.6

> In method org.apache.ignite.internal.util.IgniteUtils#workDirectory
> Ignite determine Work dir to be set, same value may be used in case
> persistence Store Folder is not set and IGNITE_HOME is not specified.
> In case work dir is not specified, temp directory is used for Ignite Work.
> But for persistence enabled case this means user DB goes to temp folder and
> may be removed later.
> User may be confused by this behaviour. See:
