Hy,
I have a corrupted index in an elasticsearch cluster. The index is
corrupted due to bad mappings. As you can see in example, there are two
fields with same name and different mappings - one is string/doc_values and
one is date, and in Lucene this is not possible, due to "doc_values"
settings.
{
"test1": {
"properties": {
"date": {
"format": "dd/MMMM/yyyy: HH: mm: ssZ",
"type": "date"
}
}
}
}
{
"test2": {
"properties": {
"date": {
"index": "not_analyzed",
"fielddata": {
"format": "doc_values"
},
"doc_values": true
}
}
}
}
The problem is that I'm not able to start the index in order to reindex the
data from it. (The error is [WARN ][cluster.action.shard ] [cluster]
[index][1] sending failed shard for [index][1],
node[b2yMUmvXQFy8LFd8ei6DZQ], [P], s[INITIALIZING], indexUUID
[I_zoR-4SS02WEfRNKFc6MA], reason [Failed to start shard, message
[IndexShardGatewayRecoveryException[[index][1] failed recovery]; nested:
IllegalArgumentException[cannot change DocValues type from BINARY to
SORTED_SET for field "date"]; ]]).
Is it possible to somehow recover the data from corrupted index and put it
in a healthy index ? (I'm using Elasticsearch 1.1.1)
Thank you,
