So before starting upgraded ZooKeeper server set snapshot.trust.empty=true in zoo.cfg or zookeeper.snapshot.trust.empty=true as java system property to solve the problem. > Upgrade to Apache ZooKeeper 3.5.7 > --------------------------------- > > Key: HBASE-24132 > URL: https://issues.apache.org/jira/browse/HBASE-24132 > Project: HBase > Issue Type: Improvement > Affects Versions: 3.0.0, 2.2.3 > Reporter: Jianfei Jiang > Assignee: Jianfei Jiang > Priority: Major > Fix For: 3.0.0, 2.3.0 > > > Apache ZooKeeper 3.5.7 has been released, HDFS and other projects have > updated the dependent zookeeper verison.
