Hi, I'm using Spark Thrift JDBC server and 2 limitations are really bother me -
1) One instance per machine
2) Yarn client only(not yarn cluster)
Are there any architectural reasons for such limitations? About yarn-client I might understand in theory - master is the same process as a server, so it makes some sense, but it's really inconvenient - I need a lot of memory on my driver machine. Reasons for one instance per machine I do not understand.
