Error trying to start the coordinator

[sumatheja dasararaju]

Hi All,

I am running into an issue while trying to start the coordinator. Any help regarding this would be highly appreciated. Here is the short error log, detailed error log is attached.

Error when starting up.  Failing.

com.google.inject.ProvisionException: Unable to provision, see the following errors:

1) Unknown provider[mysql] of Key[type=io.druid.metadata.MetadataStorageConnector, annotation=[none]], known options[[derby]]

  while locating io.druid.metadata.SQLMetadataConnector

Also attaching the common.runtime.properties file. I made sure I checked to see that the metadata database is accessible from the host (where I am trying to start the coordinator). Let me know if you need any further information. Thanks

PS: greying out some information in the properties file due to company policies.

Cheers

Figured it out. It was due to change in runtime.properties file for extensions in 0.9.2.

Hi,

Did you setup the mysql metadata storage extension and the related configurations properly ? Details available at https://druid.apache.org/docs/latest/development/extensions-core/mysql.html
