Hi, >We’re seeing (4.3.x) MDS timeouts when opening large checkpoint replicas. How much size ? The #770 ticket has the statistic of Performance with & without this fix , please cross check with your size with that.
It always better to test timing issues in the same environment , so I suggest you ,to reproduce the problem in your setup with 4.5 ( I will complex to replicate your environment to confirm ) -AVM On 10/15/2014 5:09 PM, Tony Hart wrote: > We’re seeing (4.3.x) MDS timeouts when opening large checkpoint replicas.
