Hello.
I want to disable wal archiving by setting WAL path and the WAL archive
path to the same value.
https://apacheignite.readme.io/docs/write-ahead-log
I make this change and then success restart my node first time.But I get an
exception when I restart my node second time.Is my change a dangerous
operation？Can I recover it?
Here is the exception:
[21:22:22,321][SEVERE][main][IgniteKernal] Exception during start
processors, node will be stopped and close connections
class org.apache.ignite.IgniteCheckedException: Failed to start processor:
