Elastic Date Format - elasticsearch

Question

I have specified the mapping info in the template as below:
"createdDate": {
"type": "date",
"format": "yyyy-MM-dd HH:mm:ss||yyyy-MM-dd||epoch_millis||EEE MMM dd HH:mm:ss Z YYYY||dd MMM yyyy HH:mm:ss zzz"
},
"expirationDate": {
"type": "date",
"format": "yyyy-MM-dd HH:mm:ss||yyyy-MM-dd||epoch_millis||EEE MMM dd HH:mm:ss Z YYYY||dd MMM yyyy HH:mm:ss zzz"
}
And when i tried to insert a Doc into the index i am getting the following error.
PUT my_index/MyDocType/5c7ab034-5de3-4401-8b46-7f8158618b68
{
"uuid": "5c7ab034-5de3-4401-8b46-7f8158618b68",
"createdDate": "15 Apr 2019 14:10:10 EDT",
"expirationDate": "10 Oct 2019 00:00:00 EDT"
}
And here is the Error i am getting:
{
"error": {
"root_cause": [
{
"type": "mapper_parsing_exception",
"reason": "failed to parse [createdDate]"
}
],
"type": "mapper_parsing_exception",
"reason": "failed to parse [createdDate]",
"caused_by": {
"type": "illegal_argument_exception",
"reason": "Invalid format: \"15 Apr 2019 14:10:10 EDT\" is malformed at \" Apr 2019 14:10:10 EDT\""
}
},
"status": 400
}
I can parse the String Values using following with out any issues. Not sure why Elastic is complaining while parsing the Month part of the Date String !!
SimpleDateFormat sdf = new SimpleDateFormat("dd MMM yyyy HH:mm:ss zzz");

Answer 1

As mentioned in this link, below is what z and Z means
z time zone text Pacific Standard Time; PST
Z time zone offset/id zone -0800; -08:00; America/Los_Angeles
It appears that your format is not valid Joda DateTimeFormat
Adding the correct format dd MMM yyyy HH:mm:ss z to your mapping, as mentioned below, should solve your issue.
{
"createdDate":{
"type":"date",
"format":"yyyy-MM-dd HH:mm:ss||yyyy-MM-dd||epoch_millis||EEE MMM dd HH:mm:ss Z YYYY||dd MMM yyyy HH:mm:ss zzz||dd MMM yyyy HH:mm:ss z"
}
}
Hope it helps!
