> OutOfMemoryError during host checks on 2k nodes cluster
> -------------------------------------------------------
>
> Key: AMBARI-6061
> URL: https://issues.apache.org/jira/browse/AMBARI-6061
> Project: Ambari
> Issue Type: Improvement
> Components: controller
> Affects Versions: 1.6.1
> Reporter: Siddharth Wagle
> Assignee: Dmitry Lysnichenko
> Fix For: 1.7.0
>
>
> Host checks are executed as custom actions. But each task contains list of
> all hosts in roleParams field of execution command.
> On 2k node cluster this results in 170kB overhead for each task and 170kB
> more after deserialization, which seem to be enough to cause OutOfMemory
> error.
> Workaround is to increase max heap size to 4096m.
> For tasks generated by server similar trouble was resolved by moving
> clusterHostInfo to Stage level.
