Impala Catalogd high availability

Hello Cloudera Community,

 

We have a use case where we cannot afford the restart of catalogd, as the reload of metadata takes many hours and queries are impacted during this long reload.

 

Is it possible to have multiple catalogd instances with an active / passive setup? In this case the active catalogd would act as the main catalogd and in case of failure, one of the passive catalogds would take the lead becoming active. This would eliminate the huge metadata reload time in case of failure in the catalogd node. 

 

It would be really interesting to have the feedback of the community about such setup, and see if someone has already tested it.

 

Thanks a lot for your replies
