> Currently, the credentials needed to support Hive-on-S3 (or any other 
> cloud-storage) need to be to the hive-site.xml. Either using a hadoop 
> credential provider or by adding the keys in the hive-site.xml in plain text 
> (unsecure)
> This limits the usecase to using a single S3 key. If we configure per bucket 
> s3 keys like described [here | 
> http://hadoop.apache.org/docs/current/hadoop-aws/tools/hadoop-aws/index.html#Configurations_different_S3_buckets]
>  it exposes the access to all the buckets to all the hive users.
> It is possible that there are different sets of users who would not like to 
> share there buckets and still be able to process the data using Hive. 
> Enabling session level credentials will help solve such use-cases. For 
> example, currently this doesn't work
> {noformat}
> set fs.s3a.secret.key=my_secret_key;
> set fs.s3a.access.key=my_access.key;
> {noformat}
> Because metastore is unaware of the the keys. This doesn't work either
> {noformat}
> set fs.s3a.secret.key=my_secret_key;
> set fs.s3a.access.key=my_access.key;
> set metaconf:fs.s3a.secret.key=my_secret_key;
> set metaconf:fs.s3a.access.key=my_access_key;
> {noformat}
> This is because only a certain metastore configurations defined in 
> {{HiveConf.MetaVars}} are allowed to be set by the user. If we enable the 
> above approaches we could potentially allow multiple S3 credentials on a 
> per-session level basis.
