Read from a configuration file in Nifi -


i trying read configuration file(conf.txt) in nifi. based on path provided in file want configure paths(eg:hdfs file path , input directory path) in nifi processors.

is possible existing processors or should go custom processor.

can please me on this.

you can configure custom properties part of apache nifi's variable registry feature, makes properties external file available nifi expression language expressions. using expression language, can configure many processors externally-defined variables.

conf/nifi.properties

# external properties files variable registry # supports comma delimited list of file locations nifi.variable.registry.properties=./conf/custom.properties

conf/custom.properties

my.prop1=value1 my.prop2=value2 ...

in expressions

${my.prop1}

arrays - What causes a java.lang.ArrayIndexOutOfBoundsException and how do I prevent it? -

what arrayindexoutofboundsexception mean , how rid of it? here code sample triggers exception: string[] name = {"tom", "dick", "harry"}; for(int = 0; i<=name.length; i++) { system.out.print(name[i] +'\n'); } your first port of call should documentation explains reasonably clearly: thrown indicate array has been accessed illegal index. index either negative or greater or equal size of array. so example: int[] array = new int[5]; int boom = array[10]; // throws exception as how avoid it... um, don't that. careful array indexes. one problem people run thinking arrays 1-indexed, e.g. int[] array = new int[5]; // ... populate array here ... (int index = 1; index <= array.length; index++) { system.out.println(array[index]); } that miss out first element (index 0) , throw exception when index 5. valid indexes here 0-4 inclusive. correct, idiomatic for statement here be: for (int index = 0; index <...
