As part of my Java mapper I have a command executes some code on the
local node and copies a local output file to the hadoop fs.
Unfortunately I'm getting the following output:
"Error occurred during initialization of VM"
"Could not reserve enough space for object heap"
I've tried adjusting mapred.map.child.java.opts to -Xmx512M, but
unfortunately no luck.
When I ssh into the node, I can run the -copyFromLocal command without
any issues. The ouput files are also quite small like around 100kb.
Any help would be greatly appreciated!
Cheers,
Joris
