Commit 323d8ea7312678b7a910e55ed4f74acaf3813ffc in kudu's branch

KUDU-3223: management of per-table limit by kudu CLI
Use kudu CLI to set disk_size_limit and row_count_limit on table level.
If '--enable_table_write_limit' is not set 'true' for kudu-master, kudu
CLI fails to set the limit. The table's disk_size_limit and
row_count_limit are 'N/A' when calling 'kudu table statistics'.
Only when '--enable_table_write_limit' is set 'true', can the kudu CLI
change the table limit. Use 'kudu table statistics' to check the
updated result.

> Total table size quota management for every user
> ------------------------------------------------
>
> Key: KUDU-3223
> URL: https://issues.apache.org/jira/browse/KUDU-3223
> Project: Kudu
> Issue Type: Wish
> Reporter: Redriver
> Priority: Major
>
> *Requirement description*
> In production environment, the quota management for total tables size and
> single table size of a single user is necessary. If the quota is reached, the
> write operation including insert and update is forbidden, only table
> creation, scan and delete are allowed.
> We need to allow admin to configure the quota for every user, monitor the
> quota status, and stop the write operation with an error returned to client.
> So, I hope Kudu cli can list the status. Currently, the kudu table statistics
> only gives the disk size and live row count. It is better improve this by
> adding user name for table statistics, or create a new parameter to query
> every table size for every user, and disable/enable a user's write privilege.
> Can this be configured through Apache Ranger?
> *Typical scenarios*
> # Some user has malicious operation to create a huge table, or many small
> tables, as a result, the total table size exceeds the cluster's capacity, we
> have to stop him in time.
> # When writing Kudu table through Flink, the streaming process is always
> running, which means the Kudu table writing never stopped. If we do not have
> a protection, the Kudu cluster will be exhausted someday.
