Problem: RunOnSpark sanity check queries fail because YARN cannot allocate the number of containers requested on HDP.
Solution: In the YARN configuration on Ambari, change these settings to these values:
Setting | Value |
---|---|
Memory allocated for all YARN containers on a node | Maximum available value |
Minimum container size | 512 MB |
Maximum container size | 2048 MB |
Percentage of physical CPU allocated for all containers on a node | Maximum available value |
Number of virtual cores | Maximum available value |
Maximum container size | Maximum available value |
