mysql-zipkin service is not up in kubernetes cluster

[Priyanka098]

I follow direct installation steps from https://github.com/fabric8io/kubernetes-zipkin and all services are running except zipkin-mysql , error log is

Initializing database
2017-02-23T04:59:31.155629Z 0 [Warning] 'NO_ZERO_DATE', 'NO_ZERO_IN_DATE' and 'ERROR_FOR_DIVISION_BY_ZERO' sql modes should be used with strict mode. They will be merged with strict mode in a future release.
2017-02-23T04:59:31.155661Z 0 [Warning] 'NO_AUTO_CREATE_USER' sql mode was not set.
2017-02-23T04:59:31.157307Z 0 [ERROR] --initialize specified but the data directory has files in it. Aborting.
2017-02-23T04:59:31.157331Z 0 [ERROR] Aborting

to resolve it i added following things in zipkin-mysql-cnf in [mysqld]

 custom.cnf: |
     [mysqld]
     explicit_defaults_for_timestamp = 1
     sql_mode = NO_ENGINE_SUBSTITUTION,STRICT_TRANS_TABLES

but didnot work
