Please mention in the title that this is about read support.


http://gerrit.cloudera.org:8080/#/c/17026/23//COMMIT_MSG@10
PS23, Line 10: CHAR(N)
Can you add more info about the unsupported type? E.g.
Impala type | Problem
VARCHAR(N)  | truncation can change hash
CHAR(N) | padding / truncation can change hash
DECIMAL | multiple encodings supported
TIMESTAMP:| multiple encodings supported, timezone conversion
DATE  | ?

A follow up Jira could be also created and mentioned here that would add 
support for more problematic types if possible (e.g DATE, DECIMAL, maybe 
TIMESTAMP)
