Hi All,
I am trying to send data from Hive to ES. My job keeps on getting
connection timeouts. On the ES side, i do not see any errors though.

I have tried different batch sizes and the result has been the same. ES
machines at times become CPU bound but memory never comes under strain. I have
tried tweaking below settings:
'es.batch.size.entries'='1000',
'es.http.timeout'='10m',
'es.batch.write.refresh'='false',
'es.action.heart.beat.lead'='60s'
Can this be a ES issue where it cannot keepup with incoming data load?
Thanks!
Ravi
