I am keep getting the above error in log of one of my master nodes. But I can run the following health check with no issue.
[root@awselsprdlap01 awselsprdlap01.est1933.com-esnode01]# curl -u elastic -XGET 'http://awselsprdlap01:9200/_cat/health?v'
Enter host password for user 'elastic':

1567027541 21:25:41 es_gallo_prd green 6 3 62 31 0 0 0 0 - 100.0%
It only throws error in this node.
I removed all contents from data.path, then restarted all nodes in the cluster. But I am still cannot get rid of this error, which occurs only in this node.
Any idea where I should look into?
