Hi, We will try by setting it to True. But the name of the parameter is misleading for the 3rd party store usage. We will get back, if we find issues again. Regards, Vishwas -- Sent from: http://apache-ignite-users.70518.x6.nabble.com/

Re: Flink Streamer Compatibility.

Hi, There are multiple options available to check cache contents, separate client is one of the option or you can add dependency of ignite-rest-http and use the rest service. You can also deploy Ignite Web Console and use it. The details to use any of these options are available here

Ignite + Spark: json4s versions are incompatible

Hello, Spark provides json4s 3.2.X, while Ignite uses the newest version. This seems to cause an error when using some spark SQL commands that use a json4s methods that no longer exist. Adding Ignite to our existing Spark code bases seems to break things. How do people work around this issue?

Hi Kasnacheev, Thank you very much for the response.. We use v1.9, because 2.x uses mandatory ignite native persistence(local disk) along with durable memory management(RAM), and no option for a **java heap only** cache storage. We wanted to keep away from storing anything in disk. Hence using

Hello! This is a bad error message. I believe that cache in question is no longer consistent between nodes on metadata level, and you can't fix that without full restart or at least dropping and recreating the cache. I don't think that you will get much support from community on 1.x since the
