ES 5.0.0-rc1 Index Created, but not considered while importing data to ES

I'm using the 5.0.0-rc1 version of ELK stack
I am able to create an index which is visible in the ES server

But when i try to import data using the said index, it's not considered and the data is also not loaded

My config file is as follows
input {
file {
path => ["/home/xxx/input/xxx.out"]
start_position => beginning
sincedb_path => "/dev/null"
codec => plain {
charset => "ISO-8859-1"
filter { .....
output {
elasticsearch {
action => "index"
index => "myindex2"
stdout { codec => rubydebug }

Am i missing something/some step. Any help is appreciated.
