Trying to run with multiple explorers

[rnunziata]

Trying to run with multiple explorers....not sure if I am passing parameters correctly as the system does not process.

python impala_proto.py   -l localhost:22222 -e localhost:3333,localhost:4444 -j learner   -t 0
python impala_proto.py   -l localhost:22222 -e localhost:3333,localhost:4444 -j explorer  -t 0

All I get at both terminal windows is repeated in both windows.
CreateSession still waiting for response from worker: /job:explorer/replica:0/task:1

it works if I pass only one explorer for the -e parameter
