column:  Column names can contain any Unicode character. Any column name that is specified within backticks (`) is treated literally. Within a backtick string, use double backticks (``) to represent a backtick character.
none:  Only alphanumeric and underscore characters are valid in identifiers. Backticked names are interpreted as regular expressions. This is also the behavior in releases prior to 0.13.0.

hive.display.partition.cols.separately

• Default Value: true
• Added In: Hive 0.13.0 with HIVE-6689

In older Hive versions (0.10 and earlier) no distinction was made between partition columns or non-partition columns while displaying columns in DESCRIBE TABLE. From version 0.12 onwards, they are displayed separately. This flag will let you get the old behavior, if desired. See test-case in patch for HIVE-6689.

hive.files.umask.value

• Default Value: 0002
• Added In: (none, but temporarily in patches for HIVE-2504 before release 0.9.0) 
• Removed In: Hive 0.9.0 (HIVE-2504-1.patch), replaced by hive.warehouse.subdir.inherit.perms
