nifi-replace file headers using replacetext processor
i got a bunch of files with differert headers
for files of one type,their may be two kinds of headers,i.e. the following two type(call it type1 and type 2) of files's headers
type1: a,b,c34,d or a,b,c,d
type2: d,e,f,kgg or d,e,f,g
notice that the third field names of type1 are c or c34,the forth field names of type2 are kgg or g,the field name c34 and kgg are wrong, and need to be changed to c and g
i want to change the headers only(that is, the first line) using kv pairs, key is the string to be replaced and value is the replacement value ,such as
{"c34":"c"
"kgg":"g"
"hqq":"h"
....
}
i want to do this using replacetext but the processor replacetext could only set one search and replacement value,that's the problem!!
any ideas would be welcome
