I upgraded an instance of ES from 0.15.0 to 0.15.2 by copying the existing
data files & directories across to the newly unzipped folder of version
0.15.2, adding data no longer works.
When I try to insert into the existing index using a line like:
curl -XPUT 'http://localhost:9200/twitter/fridayreads/foo_123451234' -d
I get the curl error:
curl: (56) Failure when receiving data from the peer
What can I do to check the database and is there an upgrade
procedure/process I should have followed?
Running Ubuntu 10.04
