Chronic problem in HDP 3.1 Zookeeper server and HDFS Journalnode on single node services going down

Chronic problem in HDP 3.1 Zookeeper server and HDFS Journalnode on single node services going down

New Contributor

Hello,

I apologize in advance for my ignorance. I am a new DBA and new to working with HDP.

 

I am administrating a 7 node system in HDP 3.1.

 

The past few days about once a day, 2 of the services on one of our Data nodes, the Zookeeper server and the HDFS Journalnode seem to be having Error 111 connection issues.

 

Upon re-start of the service in Ambari, it comes right back up.

 

Can someone help me figure out why this is happening? Where are the logs for these services and what should I be looking for.

 

Again I apologize for my ignorance, would really appreciate the guidance of some Gurus.

 

Thanks
