Hi,

Any clue why the below parser is failing?

**Parser**  
SPARK\_TIMESTAMP %{DATE\_EU} %{TIME}  
%{SPARK\_TIMESTAMP:timestamp} %{LOGLEVEL:loglevel} %{WORD:classname}(:)? ([%{DATA}][UN-%{DATA:userid}][(HSI|ISI)-%{DATA:sessionid}])?%{GREEDYDATA:details}

**Log Message**  
16/11/22 03:28:06 INFO batch.driver.SparkRunner: spark.executorEnv.CC\_FILECONN\_UPLOAD\_BUFFER\_SIZE=2M

From a quick look I could spot two problems:

- DATE\_EU is for dd/mm/yy dates but your date is yy/mm/dd.
- WORD doesn't allow periods.

Thanks Magnus. That was it.
