Thank you guys for the quick fix. Is there a planned hotfix release soon? Or will I have to compile from source in the meanwhile?

[zsxwing]

Thank you guys for the quick fix. Will the updated binary be available via the spark download page or will I need to compile from source?

You need to compile from source for now. If you cannot, a workaround is always updating the state in your codes. This patch will be available in the next release 1.6.1 (should be available soon).

Merging to master and 1.6

Yes, that's how I've worked around it in the meanwhile. Thx @zsxwing
