Hi All,

I have installed Elasticsearch version 5.6.4 and also I have installed searchguard for securing the cluster. But now I am unable to start the elasticsearch and below is the response I am getting in console and the elasticsearch logs were not getting updated,

elasticsearch-uat@st-clus1-es-master3:/home/elasticsearch-uat/elasticsearch/bin$ sh start_es.sh
