Question

我们有一个带有三个节点的Kafka集群。我们有一个奇怪的问题。当控制器成为第二个节点（id 2）时，zookeeper和Kafka无法正常工作。

zookeeper配置：

#static code if header at 0,0 position
import xlrd 

loc = ("path of file") 

wb = xlrd.open_workbook(loc) 
sheet = wb.sheet_by_index(0) 

# For row 0 and column 0 
sheet.cell_value(0, 0) 

for i in range(sheet.ncols): 
    print(sheet.cell_value(0, i))

kafka配置：

maxClientCnxns=50
tickTime=2000
initLimit=10
syncLimit=5
dataDir=/var/lib/zookeeper
clientPort=2181
server.1=x.x.x.x:2888:3888
server.2=x.x.x.x:2888:3888
server.3=x.x.x.x:2888:3888
