> using storage handlers.
> --------------------------------------------------------------------------------------------------
>
> Key: HCATALOG-128
> URL: https://issues.apache.org/jira/browse/HCATALOG-128
> Project: HCatalog
> Issue Type: Improvement
> Reporter: Vandana Ayyalasomayajula
> Assignee: Vandana Ayyalasomayajula
> Priority: Minor
> Labels: hcatalog, storage_drivers
>
> Currently end-users are required to specify the input and output storage
> driver using the table properties when creating tables using storage
> handlers. This is due to the fact that HCatInputFormat and HCatOutputFormat
> rely on the properties HCatConstants.HCAT_ISD_CLASS and
> HCatConstants.HCAT_OSD_CLASS to get information about the storage drivers.
> When tables are created using storage handlers, the storage handlers have
> information about the storage drivers that should be used with the table.
> Hence this information needs not be supplied in the command line.
> Example:
> create table test_table(key int, value string) STORED BY
> 'org.apache.hcatalog.hbase.HBaseHCatStorageHandler'"
> "TBLPROPERTIES
> ('hcat.isd'='org.apache.hcatalog.hbase.HBaseInputStorageDriver',
> 'hcat.osd'='org.apache.hcatalog.hbase.HBaseOutputStorageDriver','hbase.columns.mapping'=':key,cf1:val')");
> becomes
> create table test_table(key int, value string) STORED BY
> 'org.apache.hcatalog.hbase.HBaseHCatStorageHandler'"
> "TBLPROPERTIES ('hbase.columns.mapping'=':key,cf1:val')");
