problem ingesting delimited file to druid

[tayunyang]

Hi

I like to ingest delimited file to druid. However, I cannot ingest anything because my data is not parsed. I am not sure where is not correct

My tsv file is like

1, 0
2.8736, 8.29
7.10, 8.83

My task spec is below
{
"type" : "index",
"spec" : {
"dataSchema" : {
"dataSource" : "test_append",
"timestampSpec": {
"column": "timestamp",
"format": "iso"
},
"dimensionsSpec" : {
"dimensions": [{ "name" : "requested", "type" : "long" },
{ "name" : "bfee", "type" : "long" }
]
}
},
"ioConfig" : {
"type" : "index",
"inputSource" : {
"type" : "local",
"baseDir" : "/tmp/test",
"filter" : "test_append.csv"
},
"inputFormat" : {
"type" : "tsv",
"columns" : [ "requested", "bfee" ]
},
"appendToExisting" : true,
"dropExisting" : false
},
"tuningConfig" : {
"type" : "index_parallel",
"maxRowsPerSegment" : 5000000,
"maxRowsInMemory" : 25000
}
}
}

Log shows data is not parsed so cannot be published

Based on the input file name and contents, It looks like you're passing in a .csv file (comma-separated). However, under inputFormat you've specified the type as tsv (tab-separated) which is likely causing parse exceptions.

Also - you can set logParseExceptions: true under tuningConfig in order to include the parsing exceptions in your ingestion logs.
