err “java.lang.UnsupportedOperationException: empty.reduceLeft” #297
Description
hello,
After i run 100 iters, there is an err "java.lang.UnsupportedOperationException: empty.reduceLeft", it look like somthing wrong with my DataFrame data, but the same data can work well in another cluster. The different with two clusters is that:
Working well cluster:
os:ubuntu | num_cpus/per_computer:1| devices/per_computer:3(GTX1080)| total_divices:9
Wrong cluster:
os:centos| num_cpus/per_computer:2| devices/per_computer:8(GTX1080)|
total_devices:16
can you give me some suggestion? Thanks.
