I had been able to run IPython Notebook locally and connect to StarCluster
using:
rc =
Client('/home/alessandro/.starcluster/ipcluster/myfourthcluster-us-west-1.json',
sshkey='/home/alessandro/.ssh/path-ops.pem', packer='pickle')
I upgraded IPython from 0.12 to 0.13 and it worked for the most part,
though I had some trouble at times, so following the advice at
https://github.com/ipython/ipython/issues/2171 I upgraded to 0.14. After
restarting myfourthcluster I was no longer able to connect. I was still
running 0.13 locally and was able to generate the attached crash report. I
noticed that my local copy of IPython was looking for a "url" field in the
JSON file which now looks like:
{
"control": XXXXX,
"task": XXXXX,
"notification": XXXXX,
"exec_key": "XXXXXXXXX-XXXX-XXXX-XXXX-XXXXXXXXXXXX",
"task_scheme": "leastload",
"mux": XXXXX,
"iopub": XXXXX,
"ssh": "sgeadmin_at_ec2-XX-XX-XX-XX.us-west-1.compute.amazonaws.com",
"registration": XXXXX,
"interface": "tcp://XX.XX.XX.XX",
"pack": "pickle",
"unpack": "pickle",
"location": "XX.XX.XX.XX"
}
I noticed that a JSON file I had for an older instance looked quite
different:
{
"url": "tcp:///XX.XX.XX.XX:XXXXX",
"exec_key": XXXXXXXXX-XXXX-XXXX-XXXX-XXXXXXXXXXXX,
"ssh": "sgeadmin_at_ec2-XX-XX-XX-XX.us-west-1.compute.amazonaws.com",
"location": "XX.XX.XX.XX"
}
I tried adding a "url" field but could not figure out what to fill it with.
I then figured that the problem could be because of a mismatch between 0.13
on my local machine and 0.14 remotely, so I upgraded.
Now when I try the above Client command, it hangs indefinitely.
Please help!
Thank you,
