Re: Strange behaviors for Janusgraph 0.5.3 on AWS EMR
yes, the deployMode was specified in the Gremlin Console and not in the properties file, as in the Tinkerpop example, so that's way it was not explicit here.
I am not sure why EMR would be limiting anything, since any different Spark application spawns more executors. But I am still investigating this, I will compare the entire properties list (which is reported in Spark UI as well), maybe there is something different.
For the output folder, yes it is working correctly in a way: I tried executing the CloneVertexProgram and it creates 768 files, all empty... and by zero I mean 0, while any other query (such as valueMap()) returns just nothing.
