Subject [RESOLVED] Cache Entries get lost after multiple nodes started ?
Date Fri, 24 Feb 2017 11:27:28 GMT
I was able to resolve this.
I set the backup copies of each cache to 1 in the XML file. Now, I can see all data present
even if one goes down.
But shouldn't data be automatically pushed/rebalanced to other nodes at the time of shutting
down a node ? i.e. by the ignite-core capturing that event and then redistributing that data
to live nodes ?
Is maintaining a backup copy the only option to not lose data in case of node failure ?

Regards,
Neeraj

 Another thing I noticed is that if I
 stop the node which initially populated the entries, some
 entries are suddenly lost from the cache. This is really
 strange to me.

  I was able to resolve this after I
  changed the Key from AffinityUuid to a simple Integer
 which
  is auto-incremented. How does one explain the behaviour ?

   Hi,
   I have populated a cache containing a K,V pair of
   <AffinityUuid(CustomObject) ,
 CustomClassObject>.
   It gets populated fine when I start a single node
 which is
   responsible for populating the cache. I am able to
  retrieve
   all rows using Zeppelin ignite interpreter or even
 using
   web-console.
   
   However, when I start another node using the same
   configuration file used above, some of the cache
 entries
   just vanish. Is there any reason why this could be
  happening
   ? Note that this node is not performing any data
   manipulation. It is just being started using the
   $IGNITE_HOME\bin\ignite.bat script followed by
  configuration
   file name.
   
   Regards,
   Neeraj
