[jira] [Commented] (CURATOR-272) Spamming of Background operation retry gave up

    [ https://issues.apache.org/jira/browse/CURATOR-272?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16386071#comment-16386071 ] 

Firenz commented on CURATOR-272:
--------------------------------

Hello. Apache Nifi 1.5.0 (and previous) is using Curator to access to zookeeper. 

https://issues.apache.org/jira/browse/NIFI-3731

The lost of zookeeper  servers involves the "ridiculous amount of logs " (agree :))
