Same file is being written multiple times

[mridul-tamuli]

I am using Elasticsearch Dataformat plugin (version#5.6.2) with Elasticsearch (version#5.6.4) and trying to write Kibana dashboard results into a csv file. I am passing the ES query to the plugin from the Kibana dashboard. What I noticed that sometimes the plugin completed the writing of the file but it again starts the writing process for the same content after approximately 1 minute in the same file. The total no of shards is 5 and replica is 1. I am not able to figure out this issue as it is not consistent. Can anyone help me? Thanks in advance.
