----------------------------------
[~soundhearer] I think I've more context about this issue. I also was working
on this for sometime and was testing another patch last night. I'll attach
another patch soon. Sorry for reassignment to myself.
> loadDynamicPartition complains about static partitions even when they are

> Hive is computing valid dynamic partitions here:
> https://github.com/apache/hive/blob/master/ql/src/java/org/apache/hadoop/hive/ql/metadata/Hive.java#L2853
> However it later uses the specification provided by client here:
> https://github.com/apache/hive/blob/master/ql/src/java/org/apache/hadoop/hive/ql/metadata/Hive.java#L2879
> (partSpec is exactly what client has provided and partSpec.keySet() contains
> both static and dynamic partitions key)
> As a result the makeSpecFromName here will expect both static and dynamic
> partitions in requiredKeys:
> https://github.com/apache/hive/blob/master/standalone-metastore/metastore-common/src/main/java/org/apache/hadoop/hive/metastore/Warehouse.java#L580
> However since the curPath that is passed to the above method is just like
> "somePath/dynamicPart=value" which miss the static partitions and a result
> the method will ignore static partition keys then complains in log a warning
> that the static partition keys are missing. Returning false to Hive.java, a
> log warning that "dynamicPart=value" is an invalid partition will be issued,
> despite the fact that the dynamic partition has been validated before:
> https://github.com/apache/hive/blob/master/ql/src/java/org/apache/hadoop/hive/ql/metadata/Hive.java#L2880
>
> This will cause a silent data corruption in some clients. As an example spark
> will suffer from this when working with hive metastore in master branch.
> It seems that if the goal was just to warn the client, there is no need to
> ignore the valid dynamic partition.
