(5 comments)

Hi Alex,
thank you for the doc update. Added some minor comments.

http://gerrit.cloudera.org:8080/#/c/14021/4/docs/topics/impala_default_transactional_type.xml
File docs/topics/impala_default_transactional_type.xml:

http://gerrit.cloudera.org:8080/#/c/14021/4/docs/topics/impala_default_transactional_type.xml@42
PS4, Line 42: The query option applies only when integrated with Hive
            :       3.
nit: This could be in the pre-requisite note/important field. (please see my 
comment on line 60-68)


http://gerrit.cloudera.org:8080/#/c/14021/4/docs/topics/impala_default_transactional_type.xml@50
PS4, Line 50: The default table type is not transactional.
nit: this is a bit ambiguous, would be more clear something like:
Default value, the created table will not be transactional.


http://gerrit.cloudera.org:8080/#/c/14021/4/docs/topics/impala_default_transactional_type.xml@54
PS4, Line 54: The default table type is the insert-only transactional
            :           table.
nit: would be more clear something like:
The created table will be marked as transactional, INSERT queries will be 
transactional on this table.


http://gerrit.cloudera.org:8080/#/c/14021/4/docs/topics/impala_default_transactional_type.xml@60
PS4, Line 60:     <p>
            :       If either table properties, <codeph>transactional</codeph> 
or
            :       <codeph>transactional_properties</codeph>, are set, this 
query option is ignored.
            :     </p>
            :
            :     <p>
            :       The <codeph>DEFAULT_TRANSACTION_TYPE</codeph> query option 
does not affect external, Kudu,
            :       or HBase tables as these cannot be transactional.
            :     </p>
nit: These could be in a note or important block, so users are warned about the 
prerequisites and scope of the query option.

File docs/topics/impala_transactions.xml:

http://gerrit.cloudera.org:8080/#/c/14021/4/docs/topics/impala_transactions.xml@59
PS4, Line 59:       Impala does not support changing transactional properties 
of tables. For example, you
            :       cannot alter a transactional table to a non-transactional 
table.
nit: this could be in a note/important as well
