Re: Ignite Cluster Communication with SSH Tunnels

I also added 48500 mappings, so discovery could use it, but both do not use resolver for whatever reason - AddressResolver is only used for the client address - none of cluster addresses gets mapped. The only place resolver is called seems to be this one in TcpDiscoverySpi or TcpCommunicationSpi:

Re: Ignite Cluster Communication with SSH Tunnels

You set 47099 as a communication port, but I don't see how it's mapped in the resolver. I think this is the reason. -Val -- View this message in context: http://apache-ignite-users.70518.x6.nabble.com/Ignite-Cluster-Communication-with-SSH-Tunnels-tp273p8134.html Sent from the Apache Ignite

Killing a node under load stalls the grid with ignite 1.7

Hi, we are using ignite 1.7 and under some load when caches are being updated and write behind is moving along if we just kill a node, the entire grid stalls. attaching thread dumps when the partitioned caches were in full_sync mode and also when all were in full_async mode. It looks like

Hi Denis, This is really helpful. Yes, I need the original dataframe for other API. Now I am using RDD[String, Row] as type and caching dataframe using: val rdd = df.map(row => (row.getAs[String]("KEY"), row)) igniteRDD.savePairs(rdd) It works perfectly fine. Also I was able to reconstruct the

Presently, You need to covert your data frame into key-value tuples and insert them in an IgniteRDD https://apacheignite-fs.readme.io/docs/ignitecontext-igniterdd#section-saving-values-to-ignite

Thanks for prompt reply. So if I want to cache dataframe in IgniteCache, I have to do define a custom data model class(e.g. https://github.com/apache/ignite/blob/master/examples/src/main/java/org/apache/ignite/examples/model/Person.java ) as a schema of dataframe, then construct objects and

Hi team, I was trying to cache dataframe in Ignite Cache. I was able to cache generic type data elements(RDD). However each time when I use igniteRDDF.saveValues() to cache a non-generic data type(e.g. RDD), it will trigger the noSuchMethod for saveValues as following shows. I am using
