I am also experiencing this problem, with the IOException trying to write to /usr/share/elasticsearch/data/elasticsearch/nodes/49 when running:
$ sudo -u elasticsearch bash -x /usr/share/elasticsearch/bin/elasticsearch. My /etc/elasticsearch/elasticsearch.yml does not have path.data set (it is unchanged from what is shipped with the package; indeed, I haven't touched anything in the package, and did not previously have upstream's package installed either). I can see that /etc/init.d/elasticsearch sets the DATA_DIR to /var/lib/elasticsearch, but nothing is written there.
