I tried adding a primary key constraint to the suggested table
in`quotedid_basic.q`, however, I am getting an error:
` org.apache.hadoop.hive.ql.metadata.HiveException:

This error is due to mismatch of the column names. In the `addPrimaryKey`
method
[here](https://github.com/apache/hive/blob/master/standalone-metastore/metastore-server/src/main/java/org/apache/hadoop/hive/metastore/ObjectStore.java#L5724),
`columnName` gets trimmed in `normalizeIdentifier` and loses the ` `(space),
and it doesn't match with the column name from the ColumnDescriptor in
`getColumnIndexFromTableColumns` method
[here](https://github.com/apache/hive/blob/master/standalone-metastore/metastore-server/src/main/java/org/apache/hadoop/hive/metastore/ObjectStore.java#L5735).
And this happens because we don't call `normalizeIdentifier` on the column
name while converting `FieldSchema` to `MFieldSchema` in
`convertToMFieldSchemas` method
[here](https://github.com/apache/hive/blob/master/standalone-metastore/metastore-server/src/main/java/org/apache/hadoop/hive/metastore/ObjectStore.java#L2297)
. I tried adding `normalizeIdentifier` there but it fails elsewhere, and
anyway I don't think its the correct solution because we don't want to trim the
quoted identifier.
What do you think about this?
