hdfs開啓NameNode HA，報錯Timed out waiting 20000ms for a quorum of nodes to respond

當使用ambari啓動hdfs NameNode HA時，會出現如下錯誤

修改 hdfs-site.xml

dfs.qjournal.start-segment.timeout.ms = 90000
dfs.qjournal.select-input-streams.timeout.ms = 90000
dfs.qjournal.write-txns.timeout.ms = 90000

修改core-site.xml

ipc.client.connect.timeout = 90000
