Hello, Vladimir. I'm looked into
apache-ignite-hadoop-2.4.0-bin.zip/HADOOP_README.txt It contains: ``` Installation requirements: 1. Windows, Linux, or MacOS environment. 2. Java 7 or 8 (latest update is advisable). ``` Seems, it has to be updated because Java 7 is not supported in 2.4 В Пн, 05/03/2018 в 22:42 +0300, Vladimir Ozerov пишет: > Igniters, > > We have uploaded
