Subject [jira] [Created] (IGNITE-8309) Cannot change WAL mode from client node
Date Wed, 18 Apr 2018 09:18:00 GMT
Ilya Kasnacheev created IGNITE-8309:
---------------------------------------

             Summary: Cannot change WAL mode from client node
                 Key: IGNITE-8309
                 URL: https://issues.apache.org/jira/browse/IGNITE-8309
             Project: Ignite
          Issue Type: Bug
          Components: persistence
    Affects Versions: 2.5
            Reporter: Ilya Kasnacheev
            Assignee: Vladimir Ozerov


I have cluster of a few nodes with persistence region, and a few clients, obviously without
persistence region.

When I try to do disableWal(cacheName) on client node, I observe the following exception:

{code}
Caused by: org.apache.ignite.IgniteCheckedException: Cannot change WAL mode because persistence
is not enabled for cache(s) [caches=[data0], dataRegion=null]
        at org.apache.ignite.internal.processors.cache.WalStateManager.errorFuture(WalStateManager.java:759)
~[ignite-core-2.5.0-SNAPSHOT.jar:2.5.0-SNAPSHOT]
        at org.apache.ignite.internal.processors.cache.WalStateManager.init(WalStateManager.java:292)
~[ignite-core-2.5.0-SNAPSHOT.jar:2.5.0-SNAPSHOT]
        at org.apache.ignite.internal.processors.cache.GridCacheProcessor.changeWalMode(GridCacheProcessor.java:3045)
~[ignite-core-2.5.0-SNAPSHOT.jar:2.5.0-SNAPSHOT]
{code}

>From server node I can disable and enable WAL without problems. Since it's a cluster-wide
operations, I expect it to be doable from client also.
