There's no information about required MySQL version

Hi, I've been struggling with MySql related errors.

I couldn't find any information in the readme what version is required, and that it's really required.
Once I've installed it, it worked fine.

Although there are few assumptions in the schema.sh file.

• the path to mysql. (it could be also /usr/bin/mysql)
• I was getting Unknown character set: 'utf8mb4', as I had an older version installed on the server

I can not show consumer offset on my cluster 2 and cluster 3 and I got error as below:
ERROR [OffsetsQuartz.org.springframework.scheduling.quartz.SchedulerFactoryBean#0_Worker-3] - Quartz statistics offset has error,msg is null.

is this as expect?

but i can get correct consumer offset on cluster 1 if I changed cluster from cluster 2 to cluster 1.

my system-config.properties as below:
######################################

multi zookeeper&kafka cluster list

######################################
kafka.eagle.zk.cluster.alias=cluster1,cluster2,cluster3
cluster1.zk.list=192.168.137.182:2181,192.168.137.182:2182,192.168.137.182:2183

by the way , I can get correct consumer offset on each cluster via kafka-manager.

thanks

update:

it seems only response first cluster alias.

登陆账号权限控制

新版本中权限控制需要通过数据库，但是在不同的系统中，一般使用SSO进行统一登陆，新版这样的设计是否显得多余？

怎么部署

能不能写个具体的怎么部署 需要改哪些配置呢

Support for non Java based clients

I have tried kafka-consumer-groups.sh and see that it doesn't support non java based clients (producer, consumer). Does the project support clients written in go?

Versions

Kafka Version: 0.10.2.1
Go Version: 1.8

what should i do

ERR_TOO_MANY_REDIRECTS

while running the web project in idea, visiting localhost:8080,I got an error shows too many redirects.
Broswer had been redirected to "localhost:8080/ke/account/signin?/ke/accounts/signin" , which supposed to be "localhost:port/ke/account/singin?/ke",I guess , cause that when I package and deploy it in tomcat server , I made it to visit the web UI, and it shows like that.

• Is there anything wrong with the signin logic,which cause the problem of redircts?
• btw, I use nested tomcat environment , and I can visit static resources like pictures via localhost:8080/media/img/xxx.png

Is there any way mail alert via mail relay server?

As tittle, I want send alert mail from our mail relay server instead of private email, is there any solution?

Does Kafka-eagle support SASL connection?

When I setup SASL for Kafka, and connect it with kafka-eagle, the consumers section show nothing.

this while true will block multi cluster kafka offset listening

https://github.com/smartloli/kafka-eagle/blob/fd6dc90927a5d745d86ffedb758691ad010bc9bf/kafka-eagle-core/src/main/java/org/smartloli/kafka/eagle/core/ipc/KafkaOffsetGetter.java#L126

support both kafka and zookeeper offset storage

Technically, can we support both at the same time. I mean if there is any conflict or issue when using both storages ?

Matters " java.lang.ArrayIndexOutOfBoundsExcept"

when I run KE, I got following error in ./logs/error.log.

org.springframework.scheduling.quartz.JobMethodInvocationFailedException: Invocation of method 'mbeanQuartz' on target class [class org.smartloli.kafka.eagle.web.quartz.MBeanQuartz] failed; nested exception is java.lang.ArrayIndexOutOfBoundsExcept

what should I do?

Support kafka 0.10.x ？

线上运行的kafka集群是0.10.2。打开eagle后，后台没有显示任何信息，使用的eagle版本为最新的 1.1.2 错误是

感觉应该是API的不兼容，还没兼容0.10.2版本么？ 从readme文档看，0.10.x是在未来的计划中。

使用select 提示 start with a select

but i doesn't find kafka-server-start.sh file

consumer offset is wrong after change KafkaOffsetGetter to use sasl

After using startOffsetSaslListener to listen offset thread method with sasl，the old consumer offset is wrong。For example，group ”test“ logsize is 40000 and actually offset is also 40000，we can see it before。but after using startOffsetSaslListener，the offset we can see becomes 20000。And a new group don’t hava the same problem。Why it happen？How can i make the result we can see become true？

在kafka_2.10-0.8.2.2版本，当partition是0分区时，metadata.leader() == null

报错：[KafkaClusterUtils.getLogSize()] - Can't find Leader for Topic and Partition. Exiting
现象：当分区号为0的时候，findLeader(hosts, topic, partition)方法获取的 leader 为null， 导致最总获取的logSize 为0 ，实际logSize不为空，请问这是一个bug么

Consumers无法获取

Consumers 页面中没有消费者信息，zk /consumers路径下是有消费者的。
另外建议Mock message中增加上传文件功能，文件按行导入到指定主题，该功能比较实用。
