As the title suggests, the ES 2.4 instance I had running crashed due to out of java heap error. I increased the memory and restarted ES, but all of the data started showing up as analyzed. Did some more digging and found that /var/lib/elasticsearch/elasticsearch/nodes/0 changed to nodes/1.
This must have affected the mapping. I have found some documentation on how to reindex data, but I cannot find info on how to specify nodes. I am guessing I need to reindex the data from node/1 to node/0 and then delete node/1.
Any advise would be welcomed.
