Sai Hemanth Gantasala commented on HIVE-26793:
----------------------------------------------
This patch will cause build failures locally when compiled with thrift because
this change
[https://github.com/apache/hive/pull/3822/files#diff-944faa284e92a1090cd79c781b54acf30fb2ab29f78cf952576036f452577cf4R66]
The hive_metastoreConstants.java is generated file based on constants declared
in hive_metastore.thrift class. Please make the desired change
([https://github.com/apache/hive/blob/master/standalone-metastore/metastore-common/src/main/thrift/hive_metastore.thrift#L3184])
in hive_metastore.thrift and then compile hive using thrift which would then
generate the required change in hive_metastoreConstants.java class.
[~kokila19] Can you please raise an addendum patch with the above-suggested
changes?

> Time Spent: 4h 50m

>
> Currently a simple user can create a table with
> {color:#6a8759}no_auto_compaction=true{color} table property and create an
> aborted write transaction writing to this table. This way a malicious user
> can prevent cleaning up data for the aborted transaction, creating
> performance degradation.
> This configuration should be allowed to overridden on a database level:
> adding {color:#6a8759}no_auto_compaction=false{color} should override the
> table level setting forcing the initiator to schedule compaction for all
> tables.
