Sushanth Sowmyan updated HIVE-5504:
-----------------------------------
Release Note:
Allows OrcOutputFormat.createRecordWriter() to use its table property
parameters (like "orc.compress") if specified in JobConf as well. This codepath
is not called from Hive, but will be helpful to those that want to use
OrcOutputFormat as a generic M/R OutputFormat.
In addition, makes changes to HCatalog to look for certain Orc table
properties, and if present, copies them out to JobConf before instantiating
OrcOutputFormat, thus passing the properties back to it. This allows users of
Orc from outside Hive to have Orc behave as the metadata dictates.
Status: Patch Available (was: Open)
> OrcOutputFormat honors compression properties only from within hive

>
> When we import data into a HCatalog table created with the following storage
> description
> .. stored as orc tblproperties ("orc.compress"="SNAPPY")
> the resultant orc file still uses the default zlib compression
> It looks like HCatOutputFormat is ignoring the tblproperties specified.
> show tblproperties shows that the table indeed has the properties properly
> saved.
> An insert/select into the table has the resulting orc file honor the tbl
> property.
