Hi, 1. Have you tried to run it without -Dignite.job.shared.classloader=false ? It definitely has a performance impact.
2. Are Ignite nodes placed on the same machines as Hadoop? If not, it will add a huge network interaction. 3. What is the amount of the data that you have in hdfs? If it's not fit in IGFS(as I see, you have something like 90gb in IGFS), you will have a lot of data moving between memory and hdfs - it will remove old data on reading a new one every time, when there is not enough memory.
